Temptation, the third in the Solitary Tales series by Travis Thrasher, is free to pre-order in the Kindle store, courtesy of Christian publisher David C. Cook. I'd grab this one quick as it looks like a pricing error at this point.
Book Description
The third book in the Solitary Tales series for young adults, Temptation follows the soul-wrenching twists of Chris Buckley’s journey as he heads deeper into a darkness that threatens all he loves best.
As a reluctant student at Harrington High’s summer school, Chris meets a fun-loving senior girl who offers a welcome diversion from Chris’s past. Soon Chris no longer searches for the truth about the town of Solitary. He no longer tries to pierce its shadows. He no longer questions his role in its mysteries. He makes a new choice: he runs. What he doesn’t realize is that he’s running the wrong way—and is very close to being beyond any choices at all.
