Soon Gideon, Kate, and Peter are swept into a journey through eighteenth-century London and form a bond that, they hope, will stand strong in the face of unfathomable treachery.

The Time Travellers has been praised for its excellent description of everyday living conditions in 18th-century England, while also being an enlightening read for children.

Susan Shaver reviewing for Library Media Connection said that the novel was "full of wonderful description, unique historical English terminology, and lots of British flavor, the events of the first book in this time-travel trilogy will surely captivate and hold young readers.

"[1] Melissa Moore reviewing for the School Library Journal praised the novel saying "history interweaves with science, social issues in both centuries are thrown in; yet what readers will remember most is a fast-paced plot with a cliff-hanger ending and multidimensional characters who continue to inhabit their thoughts long after the book is closed.

"[2] Kristi Elle Jemtegaard reviewing the audiobook for Horn Book Magazine described it as "breakneck plotting, pungent descriptions studded with vivid period details (like the carpet of lice on the floor of Newgate prison), and the desperate plight of the two children trapped in another century give Doyle ample opportunity to display his dramatic skills.
