Harley Merlin has a lot of unanswered questions in her life. What drove her father to kill her mother? How can she know the true extent of her magical abilities? Has Wade Crowley always been this annoying? After the violent gargoyle incident that left many dead, Harley fears what other evil tricks her psychotic aunt has up her sleeve. When she discovers that magical foster kids like herself are in danger, she knows she must do whatever it takes to protect them.

 How does one become an all-powerful Child of Chaos? That’s what Harley desperately needs to find out before her unhinged aunt raises the death toll. All she knows for sure is that magical kids are missing, and they somehow fit into Katherine Shipton’s grand scheme. Now that Harley is an official member of the San Diego Coven, she feels more responsible than ever for its protection - and that of the magical world. 

Five rituals to control Chaos. That’s all it takes. Now that Harley knows her enemy’s grand plan - to become a godlike Child of Chaos and punish those deemed “unworthy” - she’s got to figure out what the heck to do about it. Many of the missing magicals are still out there, and Katherine has vowed to kill everyone Harley cares about and make her watch. So that’s fun. Just when it seems like things can’t get much worse, one of the most precious monsters of the Bestiary escapes, and Harley is sure that Katherine has her dirty hands involved.

Harley has a game plan to stop the third ritual: infiltrate the Cult of Eris and steal back her mother’s soul. But her only way in is through her devious half-brother Finch - the same guy who was Katherine’s most devoted bootlicker not too long ago. Joining a cult counts as sibling bonding time, right? Left with no choice but to break Finch out of prison, Harley must play the part of a loyal cultist.

Magic always comes at a price. Harley is a ticking time bomb, ready to detonate with uncontrollable magic. The only solution? Find the Voodoo Queen of New Orleans, make some risky deals, and balance the Light and Darkness within her - before she’s torn apart, atom by atom. If only she didn’t have a million other problems standing in her way.

Time is running out. For the final ritual, Katherine will sacrifice 12 magicals with rare abilities. Harley has already lost so much, and she can’t bear to sacrifice anything more. She will protect her friends at all costs - even if that means flying solo against the greatest evil the world has ever known. With her parents’ Grimoire, Harley finally has a weapon capable of overpowering Katherine. If only she could figure out how to reveal the hidden pages within, to perform the spell Chaos itself has written. And the spell may reveal more than she’s bargained for.

Without magic, Harley knows the odds of defeating Katherine are stacked against them. Yet a sliver of hope survives in the pages of her parents’ Grimoire. The final, mind-boggling spell entails making a deal with a Child of Chaos. But what must be offered in return? Finch wants to be the one who ends Katherine. Mother Dearest brought him into the world, and he wants to take her out. He will give anything for that chance - even his life.

An invisible city rises from the depths, led by a new savior...Prepare to expect the unexpected.

What’s a guy gotta do to appease an evil god? It’s been a year since Katherine tried to take over the world, and Finch Merlin is itching to do something other than odd jobs for Erebus, God of Darkness. Erebus promises he’ll free Finch of his servitude after he completes one final task - finding the Fountain of Youth.

Magical mapmaking is an ancient art - and also a major pain. At least, Finch can’t help but feel that way since Erebus transported him to the mapmakers’ monastery with little to no instructions. Now, he’s stranded on some Greek island until he can learn how to draw maps to places he thought only existed in legends, like El Dorado and Shangri-La.
