Summer's plans for a romantic escape to Mazatlán with her boyfriend the week before her University of Arizona classes resume disintegrate when he dumps her just before the trip. She goes anyway, planning to drown her sorrow with Mai Tais. Her plan goes awry when she wakes up beside a drop-dead gorgeous guy she can't remember sleeping with. She imagines things can't get worse until she learns this Alex has a bristly personality and, thanks to the hurricane outside, they're stuck together until the storm ends.
