Mated to the Shadow Dragon: Shadow Dragon Book 2 (Dragon Shifter Romance) - Shadow Dragon, #2

Trapped in a strange, fantastical new world with the only familiar her lover who doesn't even remember her, Elly is thrust into more trouble than she could ever imagine. That trouble includes finding out more about the Heaven Stones, the source of most of her troubles in the new world. Unfortunately, following on their heels are mysterious men with even more mysterious motives. Shade's past, too, stalks them into more problems when he's unwillingly called on to solve a mystery that involves life and death, and the space in between. Their adventures lead them up and down the city of Senexitas, where they meet foe and friend alike in their search for answers.
As they delve deeper into the seedy underbelly of the infamous city, Elly and Shade begin to realize that maybe they aren't chasing as many threads as they first believed.
