Vietnam took her first love away from her. Now it may take her next love, too. After her husband dies, Gillian Warner realizes how many sorrows she carries inside her, including unresolved grief over her first love, who died in Vietnam decades earlier. Haunted by his death in combat and a tangled web of guilty secrets, she books a guided trip to the battle site. The tours are led by cynical Vietnam War vet A.J. Donegan, who makes his living taking naive Americans on what he calls Guilt Trips, Inc. If they're looking for peace of mind, they can forget it. A prickly attraction sparks between Gillian and Donegan, with neither able to let go of the past without the other's provocative challenge. In a test of willpower and desire, they'll have to share much more than a journey to a place and a memory; they'll have to travel deep inside the walls they've built around their hearts.
