Ryker by Margo Bond Collins

When Ryker Phillips goes undercover to spy on the Idaho pack, the last thing he expects is to fall in love. As the Moonstone Pack’s lead enforcer, he’s supposed to protect the pack from interlopers, not invite one in as his mate.
Ivy Campbell has zero desire to choose any mate at all. As one of the lowest-ranking females in the pack, she’s been mistreated for most of her life. When a new alpha took over, she’d hoped for a change. But she’s right back where she was before, and she’d rather suffer the fate of becoming a lone wolf than allow anyone into her heart.
So when a new wolf shows up, she does everything she can to resist him, despite her attraction to him. And as she grows closer to the newcomer, she must determine where her loyalties truly lie. When she learns he’s keeping a dangerous secret, will she betray him or protect him?
