Aimee Easterling 
Shadow Wolf [EPUB ebook] 

The only thing worse than hiding from werewolves is living among them.
No wonder I kept some secrets, broke a few rules…and implicated my werewolf protector, Gunner, in the process. Oops.
To make matters worse, the stealer of my dead mother’s magic has set his sights on my sister a second time. As the child’s powers fade, so does her vitality until death looms on the horizon.
Can I learn to harness the power of the pack — and squash my individuality — before my sister’s life is entirely sucked away from her? And, with my recent blunders causing upheaval in the werewolf world, will Gunner be willing to help us if I choose to ask?
This second book in Aimee Easterling’s ’nailbiting’ and ’explosive’ urban fantasy series follows Wolf’s Bane.
