A pacey and action-packed time-slip adventure that carries step-siblings Felix and Zoe back to Ancient Roman times - and also, accidentally, drags a Roman girl into the present.

When 11-year-old Felix finds a message in a bottle during a trip to France, he is in for the surprise of a lifetime. Suddenly he is flung back 1700 years to Ancient Roman times, dragging his very unwilling 15-year-old stepsister, Zoe, with him.

They are offered sparrows for lunch and horse-spit as medicine, but that is only the beginning! When they ricochet forward to their own time again, Felix and Zoe discover they have accidentally brought a high-class Roman girl with them... Can they navigate the strange Roman world - from opulent city to distant sacred spring - and return the 12-year-old girl to her family before time runs out?

In this standalone companion novel to the acclaimed The Boy Who Stepped Through Time, featuring a whole new cast of characters, award-winning author Anna Ciddor has created a roller-coaster adventure that will have young readers on the edge of their seats.
