First to Fight by Mazzy King

Ever since the disastrous convoy mission that left most of his squad dead, US Marine Ayden Delaney’s life has been in shambles. He’s fled to the other side of the world to get away from the pain of the losses of his USMC brothers. He’s quickly learning, though, that no matter where he runs, the nightmares follow.
When his older brother contacts him from back home, Ayden has to make a choice: stay in Thailand, or drag himself back to California and stand beside his brother on his wedding day—and decide if he still has a future with the Corps. A chance at a real life.
And, after meeting Carmen, a beautiful and kind-hearted woman when he visits the UCLA campus to see if he can finish his degree, maybe even…love.
He’s always been the first one to fight—for his friends, for his country. Now it’s time to fight for the one person who matters most right now.
Himself.
