An abandoned opal mine. A deadly foe. And an armful of tiny baby shifters…

Spy work is rough, especially when you're undercover at a company that indulges in some pretty shady practices–like, say, stealing ancient shifter eggs. With ancient shifter babies inside them.

So it's only natural that Antelope Shifter spy Zina would draw a line in the sand. Except that now she's got more sand than she could ever have imagined – she's on the run in the South Australian desert with three precious eggs in her bag and murderous enemies on her tail, and the only person by her side is a guy she met once three years ago.

Sure, he's hot, and charming, and kind, but there's no real reason for her to trust him. And yet, he's the only person in the world she feels like she can turn to.

Prehistoric kangaroo shifter and undercover operative Trent thinks he's a pretty easygoing guy–but there are some things that can surprise even him. Like suddenly getting a desperate plea for help from the gorgeous spy who shot at him the last time they met… who also happens to be his fated mate. Not that she seems to know that.

Now they're rattling through the desert in a broken-down old car, baby shifters are popping out of eggs all over the place, and Zina still seems unaware of their connection. What's worse, she can't even appreciate a good pie floater. But she is his fated mate–and he'll do everything in his power to protect her.
