Determined to escape the gloom that has descended on Aber, Gareth and Gwen travel to Shrewsbury in an attempt to find answers about Rhun's death, about the whereabouts and plans of Prince Cadwaladr, and about Gwen's family ties to England. But when John Fletcher, now deputy sheriff of Shrewsbury, asks Gareth to help him investigate a pool of blood for which he has no body, Gareth can't refuse.

Prince Hywel has called all the bards of Wales to him for a music festival to mark the third anniversary of his rule over Ceredigion. He has invited all the lords of Wales too, including his father, his uncle, and his neighbor to the south, King Cadell. But with the highborn also come the low: thieves, spies, and other hangers-on. And when a murderer strikes as the festival starts, Gareth and Gwen are charged with discovering his identity - before the death of a peasant shakes the throne of a king.

March 1147. Assassination, espionage, betrayal. King Owain has ridden east to confront King Madog of Powys with the attempt on the life of his son. Rhys, now abbot of St. Kentigern's monastery, hopes for peace and calls both Madog and Owain to the negotiating table. Peace, however, is the last thing on Madog's mind. Recalcitrant, self-righteous, and angry, he sees King Owain's recent weakness as his opportunity and knows that Owain's own barons are circling like wolves, waiting for the chance to overthrow him.

Hallowmas 1144. With the harvest festival approaching, Gareth has returned from fighting in the south, hoping for a few months of peace with Gwen before the birth of their first child. But when an innocent foray to the beach turns up the murdered body of Prince Hywel's long lost cousin, a woman thought to have run away with a Dane five years earlier, it is Gareth and Gwen who are charged with discovering her killer.

May 1147. Gareth and Gwen have traveled to Deheubarth in the retinue of Prince Hywel. The Prince of Gwynedd has temporarily allied himself with King Cadell and his Norman relations in order to finally evict the hated Flemings from south Wales. But while the battle goes well, the celebratory feast afterwards does not, leaving Gareth and Gwen among the few left standing. And it is to them, as always, that the investigation falls and on whom peace in Wales may well depend. 

May 1148. All Dublin is shocked by the murder of a prominent merchant, but only Prince Godfrid knows that the dead man was also a co-conspirator in his brother's plan to take the throne of Dublin. With death stalking his every move, Godfrid must call upon new friends and old to find the killer - and with their help uncover a conspiracy stretching beyond Dublin's walls to every kingdom in Ireland. 

May 1144. Newly wedded, Gareth and Gwen travel across the border into England on a diplomatic mission with Prince Hywel of Wales. Within moments of their arrival, however, the mission goes awry and a murder case drops (literally) at their feet. Hindered at every turn by a climate of civil war and constantly shifting political alliances, Gareth and Gwen race to solve the murder and expose a plot that threatens not only their lives, but the life of the future king of England himself.

August 1148. The wedding of Godfrid and Cait promises to be the event of the year, and even Gwen has made the journey across the Irish Sea to celebrate. Weddings can be moments around which tensions and resentments pivot, however. So, when a monk turns up dead within moments of Gareth and Gwen's arrival in Ireland, the pair put on their sleuthing hats and get to work, racing to solve the mystery before it ruins Godfrid's big day.

It is the winter of 1143 and all is not well in the court of Owain, King of North Wales: His future in-laws are untrustworthy; the Norman lords on his eastern border are restless; and among his wedding guests lurks a cold-blooded killer.

Hugh Bradecote does not want his betrothed heading off on pilgrimage to the shrine of St Eadgyth at Polesworth, but the Archbishop of Canterbury's envoy and his entourage of monks seem Heaven sent as escorts, right up until they are captured by a renegade who wants his forger out of the lord Sheriff's cells; a renegade who loathes the Benedictines and kills for pleasure. 

March 1294. Ireland is at a crossroads. The different factions - Irish, Danish, and English - are tearing the country apart with their constant warfare. Hoping to hammer out a treaty, David calls the Irish Parliament into session. Unfortunately, some lords are far more interested in fighting than talking, and it isn't long before the conference goes awry. With the future of Ireland at stake, David finds himself caught up in a far-reaching conspiracy that puts not only his own life on the line, but his family's as well.

Christmas 1292. Time travel has meant many things to Meg, David, and Anna over the years. But regardless of the circumstances, it's always been about saving lives: their own, their family members', and their friends'. This time, it's a combination of all three.

April 2022. When an unknown gunman sends David and William back to Earth Two, Michael, and Livia are left gasping along with the rest of their universe. Accepting that their respective employers are possible suspects, not to mention untrustworthy, the pair band together in the shooting's immediate aftermath, in an attempt to put the first few pieces of the puzzle together. But when an unexpected bout of time travel upends everyone yet again, Michael and Livia realize they are on their own, and this particular puzzle is one that they - and only they - can solve.

Two years in Afghanistan; four years working for MI5, the British security service; and the death of both of his parents from cancer. At the age of 34, Callum thought he'd experienced the worst that life could throw at him. That was until his boss ordered him to open a buried file on his desk and to take it seriously. His new assignment: to detain and question a pregnant woman and her ailing husband - and, if need be, to stop them from returning to medieval Wales.

With David and Llywelyn in Ireland, the rule of Wales and England has fallen to Math and Anna. Unbeknownst to them, however, rebellious barons have tried to assassinate David and thrown Ireland into civil war. When the treachery reaches across the sea and touches Anna, she finds herself at the center of a conspiracy that stretches from Dublin to Edinburgh - and only her actions and choices stand between her family and the destruction of everything they've worked so hard to build.
