Invisible Detective

I recently read several books in the Invisible Detective series by Justin Richards, and was amazed that I hadn't heard about them before. The stories take place partly in modern England and partly in the same locale near the beginning of WWII. Combining history, mystery, and a touch of fantasy with unique but believable characters and some scary settings, these exciting books are just the sort to appeal to kids. If I knew any reluctant readers, especially boys, I'd certainly recommend this series to them. Kids of either sex who like to read will probably enjoy them a lot too.
