Shadow Codex — Tina Christopher

One witch. One shifter. One angry god hell-bent on the destruction of the world. Witch Caleigh hunts for the Shadow Codex. She has seven days to unearth it and learn the spell to banish a god before he can do the whole "wipe out the world" thing. She doesn't anticipate being joined by sexy Sawyer, the man she's had a crush on for months. After having suffered devastating loss she's no longer willing to risk her heart, so a crush is all it can be. Sawyer has one goal: fulfill his duty as alpha and protect his pack at all cost. Being sidetracked by luscious Caleigh isn't part of the plan. When he discovers they are after the same book he's happy to savor every moment with her. That's all he can do. Because bringing a human into a world where physical prowess is everything would kill her. The chemistry between them grows explosive until danger catapults them over the edge. Caleigh has to decide how much she's willing to risk. Sawyer needs to determine if his pack is really all that matters. And they both have to reevaluate the secrets they're keeping. It may be easier to banish a god than to face their inner demons.
