Greyson by Anna Blakely

Tragedy brought them together. A killer will stop at nothing to tear them apart.

For former SEAL Greyson Frost, nothing is more important than loyalty. It’s why this Charlie Team operative keeps his feelings for his best friend’s little sister hidden. But when tragedy strikes and Taylor becomes a killer’s target, all bets—and past promises—are off.
Taylor Russell is used to devastation and loss. Determined to pick up the pieces of her shattered family and start fresh, she pulls herself together long enough to deal with everything her brother left behind…including his ruggedly handsome best friend. But before she can begin her new life, Taylor discovers a side to her brother she never knew. One that sends her straight into a killer’s path.
Having no one left to turn to, Taylor puts her life—and her heart—in Greyson’s hands. Before long, they both find the love they’ve been missing, and a future someone is out to destroy. With the help of his teammates, Greyson will risk it all to save the woman who owns him. Because a life without Taylor isn’t an option. Not anymore.
