Dragon Bound (Elder Races Series #1)

Dragon Bound (Elder Races Series #1) - Thea Harrison,  Sophie Eastlake There was no real big shocker with this book. I do have a few questions, though.
1). What exactly is a "machete" smile and why does Dragos keep flashing it?
2). What is Pia's "real" name? There was this big build up with it and no reveal. Why make it such a big deal and then not tell us?
There were some fun moments and some predictable moments but overall, not awful. I plan to read the next one.
