Title: Jayden's Rescue
First published: March 30, 2002
Description: Jayden’s Rescue is a mathematical adventure novel about three kids who find a magic pencil capable of solving any math problem all by itself!  Sounds pretty neat, doesn’t it?  Perfect grades on tests, happy parents... but nothing is free in this world.  Easy math problems create new “hard” problems, like a weird book with living characters popping up out of nowhere and a struggle with a creepy villain called Rechner.  Jayden’s Rescue is chock-full of math puzzles that the kids have to solve before their time runs out and Rechner catches up to them.  Then there is a mysterious queen called Jayden.... but enough said.  Here is a sample puzzle:

I have a little sister; her age is eighty-four.
I recently turned ninety — a fact that I deplore!
When we were so much younger, I was three times her age.
How old was I?  Go figure and be like me — a sage.
