Book Series: The Missing Series

Katherine and Jonah have just saved the Grand Duchesses Anastasia and Maria, as well as their brother the tsarevitch Alexei Romanov. Although the Romanovs are devastated that they lost the rest of their family, they are happy that they still have each other and are safe. But they weren’t the only ones saved: Leonid, Alexei’s faithful servant and friend, was also whisked away to the time hollow. Will he be able to accept his fate?

Thirteen-year-old Daniella McCarthy begins receiving a series of unusual phone calls right before her family moves from Michigan to Ohio. How is it that total strangers seem to know more about her background than she does? And could it be possible that these strangers also know something about her future?

After traveling through history multiple times and finding out his original identity, Jonah thought he’d fixed everything. But some of his actions left unexpected consequences. His parents—and many other adults—are still stuck as teenagers. And now Jonah has a new sibling, an identical twin brother named Jordan.

As odd as all this is for Jonah, it’s beyond confusing for Jordan. How does everyone in his family have memories of Jonah when he doesn’t? How can his annoying kid sister Katherine speak so expertly about time travel—and have people from the future treating her with respect? A few rash moves by Jordan send them all into the future—and into danger. What if he’s also the only one who can get them back to safety, once and for all?

“A satisfying end to a long-running series.”

It’s morning as usual at the Skidmore household—until Charles Lindbergh, the famous historical pilot, appears in their living room. Jonah can hardly believe his eyes—and then Lindbergh grabs Katherine and vanishes again. And that’s not all. Chip, Andrea, and all the other children from the plane have disappeared too. And worst of all, Jonah’s parents and all the other adults in his town have de-aged into children.

Jonah is the only one left, and the only one who can save everyone. With the help of de-aged JB and Angela, he has to collect the clues. And they lead directly back to Gary and Hodge, and a terrible plot that could mean the end of everything Jonah has ever loved. Can Jonah put the pieces together before time runs out?

“Plenty of well integrated backstory lets this lively series continuation stand on its own… an entertaining and informative way to connect young readers to history.”

Jonah thought that after his last adventure in 1903, he and his sister Katherine would have a break from time travel for a while. For the first time, he’s willing to look into his own identity in the past, and he thinks this is his chance.

Trapped without a fully working Elucidator, the three kids still hope they can escape and save the lives of Anastasia and Alexei Romanov.

But is it possible to change time that much when modern-day scientists have identified the entire Romanov family’s remains?

“The story continues with the suspense fans have come to expect in this entertaining and discreetly educational series… this story has great potential to spark interest in a historical event while keeping young readers entertained and fascinated.
