I received an electronic ARC from Macmillan Children's Publishing Group through NetGalley.
This is a delightful series and the latest book doesn't disappoint. Bell opens the story with Suzy and her parents preparing for dinner with the Train's team. From the first humorous interaction, the misadventures launch and the whole family joins the Posties as they set off on a Gold Stamp Special delivery. The delivery turns out to be a rather interesting book who not only talks but pulls words from everywhere around it. In order to return it to its home, the team has to locate a lost land and help boost a small rebellion. As a plus, they locate Aybek and save the world from the latest of his schemes.
No spoilers but the action moves steadily and readers are pulled in as part of the dangers and adventures. Bell's writing style appeals to middle grade readers and will trigger their imagination. They can easily envision these settings from the word pictures and build this world in their minds. Though several loose ends were wrapped up, I hope the adventures continue.
