Gray Card by Cassandra Chandler
Is he after her heart or her planet?
Evelyn Chambers is a nerdgirl and proud of it. When she finds out that her drop-dead gorgeous best friend is an alien general with only three days left on Earth, she has to wrap her head around too much at once. Aliens are real, and if she wants to keep hanging out with one, she’ll have to marry him!
Adam Smith has never seen a planet as beautiful as Earth or a woman as enticing as Evelyn. His government wants him to re-enlist, but when Evelyn suggests marriage to help him stay, Adam realizes that what he really wants is her—and he’ll sacrifice everything to be with her.
Can he convince his government—and Evelyn—that he’s looking for more than a Gray card?
