Umber Heart

The Petra Graves Chronicles #10

by Morgan Quaid

Petra and Fenris are finally united, but the worgen is still bound to the dreamworld by Morpheus’s curse and time is running out to free him from that bond.

Leviathan, a vast cosmic beast that threatens to devour all magic in the Axis worlds, is coming and if Petra can’t unbind the curse before it strikes she could be stuck in the dreamworld forever.

So, why not throw in a full-scale rebellion for good measure?

Book ten in the Petra Graves Chronicles sees our hero leading the charge in a rebellion against Morpheus and his Blue Bloods, while attempting to get to the source of what is keeping Fenris bound to the strange dreamworld.

Written in first person perspective, the book gives rare insight into the thoughts, motivations, and quirks of some of the most intriguing characters within the series. You’ll get to see the world through not only Petra’s eyes, but also Fenris, Max, Nina, and even a few others!

The clock is ticking, but then, isn’t it always?

Can Petra lead a rebellion, free her lover, and get back to the Stone in one piece before the clock strikes doom?
