Stuck in London for one of her mom's work trips, Skye Humphries can't help holding a grudge when she ends up roped into a summer tour group with Philip-who-crushed-her-heart.

If Skye had known her choices were between summering with Philip or being sacrificed to the god of the skies, she might have changed her attitude. Now she must figure out what's most important to her--getting even for the past or having a future.
