My real life friends are gone. My online friends are just a bunch of liars. For a while I used you and your horoscopes to give me hope, but now I realize how stupid I was. Mr. Selenski tried to warn me, but I wasn't listening. I guess I didn't want to hear. I can't believe I've been writing to you like this. You must have had a good laugh. And here I am doing it again. You won't be hearing from me anymore. Unable to attend school while she battles cancer, fifteen-year-old Kaleigh Wyse tries to complete her classes online by correspondence. Developing a science project on astrology, Kaleigh enlists other online learners as study participants. What starts as a collaborative and supportive project based on the scientific method, slowly becomes unwieldy and then flawed when it is apparent that all the project participants are hiding vital clues about their identities. As Kaleigh struggles with the effects of chemotherapy and radiation, she is forced to examine the assumptions she has made about others and the manner in which she presents herself to the world. Sun Signs is a compelling story that examines the danger of blind faith in an electronic age and the ease with which our identities, in the absence of traditional clues, can shift and change. Told entirely through e-mail and online communication, Sun Signs is Shelley Hrdlitschka's sixth novel from Orca Book Publishers. Her other books include Dancing Naked, a CLA Young Adult Honour Book, and Kat's Fall. Both have been nominated for ALA's Quick Picks list.
