Alter (Entwined #1)by Lilliana Anderson
Mia has a boyfriend Eric, but she is attracted to Cayd. Mia apparently starts having memory losses and blackouts. During her blackouts she acts extremely sexually aggressive around her boyfriend. This is a fast paced, well written, at times erotic story. I liked the characters and I thought the doppelgänger storyline was really interesting. I am interested in reading the next installment of this series to see what happens to these characters. 5 stars.
