Kyle Valenti can't sleep. One year after the death of his friend Alex, he's haunted by terrible nightmares. Kyle knows Alex didn't commit suicide, but was murdered by the treacherous Tess, one of Roswell's no-longer resident aliens. Kyle even helped her kill him, completely oblivious at the time due to Tess's mind-control machinations.
If anyone can help Kyle come to grips with his tortured psyche, it's Isabel Evans, whose distinctive alien power is the ability to Dreamwalk - literally to enter another person's mind, while sleeping. Isabel thinks it's a bad idea. She's never done exactly what Kyle is proposing, or at as deep a level. She's afraid she might end up hurting Kyle more than helping. Once she decides to try anyway, she discovers a potentially worse problem than doing inadvertent harm to her friend - having entered his deepest dreams, she just might not be able to find her way back out...
Ruditis writes the Roswell characters wonderfully, and has a brisk, easy-to-read style. He doesn't complicate the plot with too many references to past series events, but only those necessary to the story. All the characters get a pretty fair share of air-play, so to speak, though it's definitely an Isabel story. Liz and Max have a less-interesting subplot, taking care of a wounded pre-teen cousin of Liz's, which largely comes off like an after-school special but allows for some character exploration of the teenaged alien leader and his human girlfriend.
This is really a simple and straightforward story, rather like a very good episode of the T.V. series. What makes it shine is the writing of the characters, and the depth of feeling between them. It's short and sweet - very sweet, and very good.
