I wanted to read this one after seeing my sister's review of it. She and I agree on dragons, and she gave it 5 stars. 
 So we've got a dragon shifter and we've got the Best Friend's little sister trope going on. Already I'm hooked. 
 It was really good. It was "Oh wow, I want to read the sequel NOW"good. Except the sequel doesn't come out until October 1! So now I must wait...
