Bound By Ice and Fire by Jaime Rush

A feisty Dragon shifter, a cool fallen angel, a dark evil, and a lot of heat!

After her father falls victim to a serial kidnapper, cunning Dragon shifter Lyra Slade is determined to rescue him. When she discovers a clue to his disappearance that leads her to a sexy but aloof stranger, she knows she shouldn’t trust him to help her, but she’s run out of options.
Archer Grant, the descendant of fallen angels, is reluctant to aid the beautiful dragon because her evidence implicates his own brother. When his brother also goes missing, Archer must work with Lyra to uncover the truth.
Even as a supernatural desire grows between the angel and the dragon, they are hunted by an evil force. Faced with the deadliest of dark magick, can even love save them?
