Teen Reviewer Jillian Wolf also read The Seventh Door, book three of Bryan Davis' Children of the Bard series. In this fantasy-adventure, teenage Matt and his mother Bonnie must stop the apocalypse by traveling through seven doors (each one containing a different evil). Opening the final door will either doom or save the world, but they won't know until they're there.
"The Seventh Door will keep your attention from the first page. With fast-paced adventure, breath-taking fights, evil villains, heroic characters, and loving sacrifces, you won't be able to put it down." --Jillian Wolf
Jillian recommends this book for ages 13 and up.
