Blush: This is a sensual romance (may have explicit scenes, but not erotic level).

Rebel Angels, Book 2

Alyssa is a Rebel Angel, semi-Fallen, like Gideon before her. Cursed by her own words, she is unable to distinguish truth from lies—even her own. She has sworn to protect her ward Rosalind from the forces of evil. But without discernment, how will Alyssa identify friend from foe? Prince Sariel of the Angelic Order of Grigori, the oldest and most powerful of all angelic beings, has endured thousands of years of celibacy for the sins of his race. It's his duty to determine if Rosalind is a Nephilim and perhaps destroy her. When Sariel comes for Alyssa's ward, more than the girl's fate hangs in the balance. Never before has he felt such dark desire as Alyssa stirs in him. The Daughters of Man are forbidden Sariel...but is Rebel Angel Alyssa?
