Wyvern’s Angel by Deborah Cooke

Bond is a secret spy for the Gloria Furore space pirates, a former member of Princess Anguissa’s crew, and a fallen angel with a taste for forbidden pleasures. He can’t resist the temptation of bad choices. He knows he should disappear from Incendium before Anguissa discovers his deception, but he isn’t counting on her enticing younger sister. Bond should know better than to get involved with a dragon shifter princess, but Percipia knows how to get exactly what she wants from him. She offers him a challenge, with irresistible side benefits, and Bond finds himself snared. He should walk away and he knows it, but Percipia’s brand of persuasion feels too much like heaven for Bond to ever want to stop…
