Warm and Fuzzy — Ann Somerville

Daniel wants to be an engineer, but when his parents die in an accident, he gives up his studies and takes a office position to support his young brother and sister. He hates his new job, but never expects to find himself in serious danger, or to need help from the amazingly tall, kind and good-looking Spen, his friends, Julian, Leo and Zachary, and, of course, their clever kems.
