Rae And Essa's Space Adventures — Donna Maree Hanson

In Rayessa and the Space Pirates, Rae made a startling discovery about her past. Now her twin sister Essa has her own adventures to pursue.

Essa Gayens is starting to accept her sister Rae into her life, sharing a dorm room in their swanky private school on Earth. Smarter, savvier and more in touch with the world than Rae, Essa's feelings of superiority and advantage are shaken when their mother goes missing, along with Rae's boyfriend, Alwin. 

When Rae takes off after them into outer space, Essa is spurred into action. Very soon, Essa is hot on her trail, sneaking out of school, bribing officials and begging Captain Thorn Hanover to take her on his ship.

Thorn is a hunk, and Essa is thrilled with the prospect of an interesting trip, but Thorn has no interest in a spoiled rich girl. Not only does he reject her advances, he sets her up on the chore roster and expects her to work for her passage.

Essa has never been anything but a pampered princess, but both Rae and Thorn are challenging her to dig deeper, to be more. But to aspire is to risk failure, and Essa has never really risked anything before. Can she start with her heart?
