Declawed

When Logan hurt the scientist who captured him, she had his claws ripped out as punishment. He's rescued, along with two others, by Shawn, the man he knows is his true mate. Scared and ashamed, he runs from Shawn, knowing he could never be an equal. Shawn is an Enforcer and follows after Logan when he leaves, knowing his mate is unable to defend or feed himself. It's not out of pity, but out of love.
In order to fight Logan's demons, however, he has to teach Logan that love heals, it doesn't destroy. But everything changes when Logan finds out he's expecting a child, engineered from the very scientist who took away his claws.
