The second in the Isaac Turner investigates series, The Forbidden Atlas, sees Isaac and Harriet in Paris receiving an award for their heroics in The Clockwork Conspiracy (you can read my review here), however, things don't go as planned and an attempt on the life of businessman Balthazar Blaise sees Isaac and Harriet drawn into an underground world where a stolen letter and a missing map will lead to a long forgotten secret and a whole world of danger.

The Clockwork Conspiracy was hugely exciting and I've been looking forward to reading the sequel ever since I finished book 1! It was wonderful to be back with Isaac and Harriet again, especially as this time they are in Paris, a city dear to my heart. It was brilliant to be able to visualize everywhere they went (the catacombs and Père-Lachaise have long been on my list of places to visit and I'm now even more determined than ever to visit them next time I'm there).

The book is full of danger that will delight readers. Bouyed by their success in London, Isaac and Harriet are determined to get to the bottom of what is going on, which leads them to some incredibly dangerous situations (at times, I really felt for their parents!).

Like The Clockwork Conspiracy, The Forbidden Atlas is a book that excites and thrills, making it a read that is impossible to put down. With twists and surprises to keep readers on their toes, Sam has another guaranteed hit on his hands, which works as a stand-alone but is even better if you've experienced the adventure of The Clockwork Conspiracy.

Publishing 27/2, secrets, lies and daring all weave perfectly through the streets of Paris in this brilliant book that is even better than book 1. The Forbidden Atlas definitely needs to pre-ordered.
