Tyrant by Lily L. James

Lark has every reason to stay away from Tyrant: he’s her brother’s best friend, the prez of an outlaw MC, and he does not know her daughter is his. But will he let her slip away again?

Never thought I’d see her again—Lark, my best friend’s baby sis, always off-limits. Until that one reckless night five years ago when we crossed every damn line. She made it clear she wasn’t into ridin’ with a biker, and I get it—her brother got locked up ‘cause of the club, and a lotta bad shit followed.
Now, Lark’s back, with eyes full of secrets and a little girl who looks way too much like me. She denies it, but every time I look into that kid’s eyes, it’s like starin’ in the mirror.
Trouble’s ridin’ close, and someone’s gunnin’ for Lark’s secrets. But I’m here, standing guard.
She thinks she can keep her distance, that I still see her as Raiden’s kid sister. She’s dead wrong. This time, I ain’t lettin’ her go.
This ride? It’s gonna be wild. But hell, it’s gonna be ours..
