These two series are filled with plenty of magic, mystery, adventures, twin speak, ghosts, time travel, wizards and surprises that will keep your MG/PT swiftly turning pages and asking for the next book in each series. Both boys and girls enjoy the two series. Seeing your kids reading will make parents happy too because their reading scores will improve in school. It’s a win win for everyone!

Remember parents, JemsBooks never has anything that is unsuitable for children all ages. Each book carries important life lessons for your children to learn while they are having a fun time reading these entertaining stories.

I bring the two series together in book 4 of Davey & Derek Junior Detectives: The Case of the Sad Mischievous Ghost. The characters come together to solve the mystery of this ghost who inhabits Abby & Holly’s old Victorian. Begin with book 1 of each series and discover the magic and unforgettable characters. I assure you that your kids will be hooked and want to read both series to find out what happens next.

I thoroughly enjoyed creating these two series and hope to begin a new one in the near future. Watch for the news about this new series. I felt like a kid again as I wrote the dialogue between the twin brothers, Davey & Derek, and with the cousins, Abby and Holly. Introduce your kids today to this entertaining and multi-award-winning series.
