The beckoning shadow

"Vesper Montgomery can summon your worst fear and turn it into a reality--but she's learned the hard way that it's an addicting and dangerous power. One wrong move and you could hurt someone you love. But when she earns a spot in the Tournament of the Unraveling, where competitors battle it out for a chance to rewrite the past, Vesper finally has a shot to reverse the mistakes that have changed her forever. She turns to Sam Hardy, a former MMA fighter who's also carrying a tragedy he desperately wants to undo. However, helping heal Sam's heart will mean breaking her own, and the competition forces her to master her powers--powers she has been terrified of since they destroyed her life"--Amazon.com.
