Calvin and Camden Luna—why yes, their dad is a big baseball fan—have moved around the world with their parents. Their father has been in the military since before they were born. Proud of their father and uncles and all they’ve done, neither of them is sure the military is for them. Cam is a fantastic baseball player and Cal loves the science of everything. Haven’t they given enough? Tristan Nolan and Maddy Holt both grew up as military kids too, but neither of their fathers moved them around as much as the twins. Maddy wants to save the planet and capture the heart of Calvin Luna… if he’d only open his eyes. Tris has grown up wanting to follow in the footsteps of those before him. But can he be himself—out and proud—serve and protect his country and end up with the one he’s loved for as long as he can remember? What can happen when you grow up a military brat with the ties that they have with their fathers’ close friends and their families? Find the love of your life almost from the start? Or find out that maybe you’re all too close for anything else?
