Magic Lessons is the second book in the Magic or Madness trilogy.  At this point in the series, Reason, Tom and Jay-Tee know the truth about magic. They have to decide whether they’ll use their magic and die young, or whether they will never use it again and go insane. Tom begins to have to lose his innocence, Jay-Tee has to face the consequences of her actions, and Reason begins to look at things in a new way.

Magic Lessons continues in the same easy-to-read style as the first book, and explores the consequences of using magic in Reason’s world.  If you are looking for other books featuring magic, then I highly recommend the Circle of Magic series by Tamora Pierce.
