Oops, I Summoned a Hellhound And My Ex Regrets

A single typo in a Christmas letter meant for Santa lands on Satan's desk instead, and he sends the narrator a devoted companion: a Cerberus hellhound. Worn down from being the walking wallet for a smug, unfaithful cat-shifter ex and a pampered sister, she decides to cut them both off for good. Her new pet is no ordinary puppy, though, and it shifts into a dangerously handsome alpha whose possessiveness runs deep. Now her former tormentors must watch her life change in ways they never saw coming.
