Kyra Greene is out of this world-literally. Jacoby, her fire dervish, has been lost in the Nether for weeks. Only Kyra can find him but not without help from her estranged father. There's only one snag in that plan. Daddy is dead.

To save Jacoby, Kyra will travel between worlds with her band of misfit creatures. And this time, she won't be facing ghosts from Mason's past. She'll be going head to head with the distant dryad branch of her family and maybe digging up a few ghosts of her own.

Grimalkins Don't Purr is the fourth book in the Valkyrie Bestiary Series.
