Trapped Between Two Worlds - The Space in Between Us, #2

It had been seven long years since Kat and Jack went to Metagalactic Space Camp. The chances of them ever even speaking again were slim to none. They are now in college, where everything is completely different. What they don't realize is, once again, they've been led right into each other's arms. The battle isn't over yet. Just as they least expect it, they are faced with more challenges than they ever had before.
 Through the conflict, tears, and overwhelming decisions, their love for each other is strengthened, and they vow to stay with each other until the end. Little do they know they are about to face the most agonizing challenge of them all.
