First Contact. Heroes of Olympus, #1

Mikhail "Wolf" Rossov and Gareth "Gunner" Gruffyd are part of a joint Navy SEAL and Army Ranger team that have been tasked with a new war. One that needs to be kept from being discovered, at all costs. Out on the job, they end up saving a woman who turns out to be more than they could have believed. Camilla Berry is a kindergarten teacher. The most dangerous part of her job is a wide spread flu epidemic in her class.
Being a teacher is all she's ever wanted. She never thought she'd soon be part of something bigger. Kidnapped to become a pawn in a dangerous, violent game, Camilla has only one hope-for her two men to come to her rescue, before it's too late. She knows that they would walk through the fires of hell for her. But will they make it in time?
