Whenever Jake and Marisol get together, adventure follows. They have their late Nana to thank for that. Her epic trips and treasure hunts were legendary.

With the whole family reuniting for one last summer vacation at Nana's home, the cousins are prepared for an extraordinary trip of their own. Following a map Nana left behind, Jake and Marisol sneak out to a nearby lighthouse--then accidentally slip into another world

The World Between Blinks is a magical place, where all sorts of lost things and people wind up. Everywhere they turn, the cousins find real mysteries from history and a few they thought were just myths, from pilot Amelia Earhart to the fabled city of Atlantis.

But the man who holds the key to Jake and Marisol's journey home doesn't want to be found . . . and if the cousins don't catch him fast, they could end up lost in this world forever.

This first book in an exciting, fast-paced fantasy adventure series--featuring fun, interesting facts about history--is perfect for fans of Chris Colfer's Land of Stories and Margaret Peterson Haddix's The Missing series
