Checkmate — Annmarie McKenna

What's an alpha shape-shifting wolf to do when the woman pre-destined to be his mate no longer trusts men?

After returning home from an eight-month security job, Eli Graham is ready to claim his best friend's little sister as his mate. He'd put it off for years, thinking he was doing the right thing by waiting. Instead of the stubborn, independent, carefree girl he left behind, Eli finds a shell of the woman he once knew.

Having lived through a near fatal attack, Nikki Taylor has hidden herself away from the world. Now the time has come to face head-on the one man who could devastate her completely, Eli Graham. She's loved him forever, craves him, body, heart and soul, but he's never treated her as anything but a little sister.

When Nikki witnesses a murder, she has no choice but to rely on Eli's expertise. While guarding her from the man bent on wiping out a witness, Eli shows Nikki that he'll not only protect her body, but he'll show her just what it means to be a wolf's mate.
