Donovan’s Girl by Merel Pierce

No one should be alone on Christmas…
When Donovan checks in on the widow of a recently-deceased enforcer, he gets more than he bargained for.
Liv is alone, grieving, and going into heat.
Worried what she might do and unable to resist the instinctive need to care for the sweet, damaged Omega, Donovan decides to stay and see her through it. Whether she likes it or not.
