Dragon Eggs Under the Tree by Maggie Hemlock

Omega dragon, Stellan, has this single parenting thing down to a T but when he signs up for some holiday help, he stumbles into the alpha dragon he never thought he’d meet: His true-mate. A retired gladiator turned teacher, Brender, is everything Stellan hoped his true-mate would be. At least, he would be, if they could figure out how to mesh their lives together this holiday season.
When family obligations collide, will these two Starscale lovers be able to get it together before they have a dragon egg under the Yuletide tree?
