Sand, Surf and Sunnie. Boys of Summer

There are lines friends don't cross, until crossing them is the only thing worth doing. Brandon and Zeke, best friends since childhood, made a pact to never to go after the one thing they both wanted-Sunnie.  But there was never any rule about being attracted to her. Sunnie always thought she'd have the perfect normal life by now but every guy she dates turns out to be a bigger dud than the last. It's a shame her two best friends, Brandon and Zeke are off limits.
Until that one day when she needed comfort and everything between the three of them shifts, a whole new relationship is opened up and with each encounter becomes more intense. For Sunnie, it's an unexpected complication. She's seen what more than two people in a relationship looks like and it isn't what she wants for her future, except she can't deny either of her best friends. Can Brandon and Zeke do more than seduce Sunnie into their bed?  Can they persuade her to gamble permanently on the strength of three?
