There was a fairly small group in attendance, which allowed the discussion to be rather informal.
Although both Amy and Lauren have been writing since they were kids, and have written for television, Reboot (first in a duology) and Parallel (a standalone) are their debut novels. Both of them also have books being released next May.
Michelle had already published four adult thrillers before taking a crack at writing for teens. She has published two of the three books in the Persefone trilogy (Don't Turn Around and Don't Look Now) as well as a standalone called Strangelets. The third book in the trilogy is due next fall.
After the requisite signings and picture-takings, I browsed the stacks for a while, and managed to limit myself to buying only two (more) books, Maggie Stiefvater's The Dream Thieves (the second book in The Raven Cycle) and Enchanted (The Woodcutter Sisters Book 1) by Alethea Kontis.
Reviews of Parallel, Reboot, The Dream Thieves and Enchanted will be posted on Teen Tuesday in coming weeks.
