All I Want For Christmas Is Boo by Tylor Paige

Lumen has lived through enough horrors to last a lifetime. After losing her entire family in a violent attack on a mall last Christmas, she becomes a recluse and moves to northern Michigan to escape... everything. Developing agoraphobia wasn't on her Christmas list, but neither was falling for a complete stranger who happens to be the very reason she's the way she is.

Tobias never expected a favor for an old friend to change his life. A simple blind date photo session turned into an obsession he couldn't get rid of. Until Christmas rolls back around, and his photographer friend requests one final favor. A home invasion of the person who robbed her of her livelihood when she testified against her boyfriend.

Lumen.

It's the perfect plan. How can she run, if she can't leave her house?

All I want for Christmas is Boo is a 100 page home invasion horror romance novella. It features one mf couple and has a HEA.
