Book of Mysteries Becky tells me is a casual game but looks as if it will remain a mystery as InteractCD does not seem to have it on the list. I will try again, again thank you 1 and all.
According to descriptions that I found, I believe the "Book of Mysteries" is also called "Zoom Book". It is a casual game that you can get at BigFishGames.com. It is put out by Mumbo Jumbo and the characters have the same names, John and Linda. It appears the name is possibly going to change when it is released to retail stores. The game may also be available from some other online download sites, but I do know it's at Big Fish. Take a look, it might be the one you want.
Have fun!!
