Not bad, story contains the standard formula of most novels written these days. The female protagonist Kate, is orphaned and doesn’t know she is a “...insert mythical/paranormal/exotic character..” (dragon shifter). Enter the 2 rival princes, Craig the regular bad boy (half demon half human) and Forrest the perfect (dragon shifter) prince to create a standard love triangle.
Craig steals a sword, gets injured, meets Kate who takes him home and her adoptive witch mother heals him. She’s bumps into Forrest, they all have a fight and the three of them accidentally get sucked through a portal into strange land, which is infected, where they have to band together to survive. Kate obviously finds out some of her past, she’s the last of her kind and that saving the worlds is her destiny.
