Strange Flesh by Michael Olson

Heartache and a passion for hacking have comprised James Pryce's post-college years. Unsurprisingly, when he's offered the chance to work for his lost love, Blythe Randall, James quickly takes the job. She and her brother, Blake, need his cyber-spy services to track down their wily half-brother, Billy, who's sworn to destroy Blake, and has the cash to back up his threats. James's investigation launches him from a lifestyle of casual sex with strangers into a virtual reality of deviant sexual behaviour. But his involvement in this online world of depravity and his cover as a video journalist start to bleed into his real life when he becomes involved in a project to develop virtual reality sex toys. By the time he realizes the truth, it may be too late for him to escape his carnal new reality.

What does it mean to be respectable? In the world of Mr. and Mrs. Baker, it means bringing up your daughter to be a lazy, selfish girl who is unable to do the simplest tasks for herself. I'm talking about the protagonist of House of Many Ways, of course: Charmain Baker. She's assigned to house-sit for her great aunt's uncle while he's away being treated for a mysterious illness. Surviving in his house requres a knowledge of magic Charmain doesn't have; luckily, an apprentice magician arrives to help her with the day-to-day chores, and with unravelling the mystery she's been drawn into. Can Charmain get her nose out of a book in time to save the kingdom?

Memory by Linda Nagata

Jubilee is a rambunctious child in a dangerous world, but her childhood is cut short when her brother, Jolly, is taken by the silver. The silver is by nature unpredictable. Sometimes it creates, sometimes it destroys, but it is always deadly to the players it touches. That's why she's so disturbed when, just before being taken, her brother tells her that he called the silver. Years later, a stranger appears out of the silver looking for Jolly. But no one can survive in the silver, and Jolly was taken years before. Troubled by the questions this man raises, Jubilee sets out to discover the truth of her brother's disappearance.
