Staff Reviews

I've read all he's written and was over the moon to get my hands on his newest book. The Lost Kingdom is full of adventure and amazing inventions. A young boy sets out on a mission in search of a mythical colony to align with against the French 1750's America. Aboard a flying ship full of brilliant philosophers, young Billy is thrown into intrigue and danger. I raced through this book and loved every minute of it. Besides being a fantastic storyteller, the reason I fall in love with Matthew Kirby's books every time is his gift for creating full, compassionate, and real characters. They are believable and stay with me long after I've finished the last page. His characters deal with emotions and feelings that we all encounter in ways that give me pause.

The Lost Kingdom is no exception. Billy wrestles with the realization that his father has flaws and prejudices that are impossible to look past; it's tender and painful and sticks with you. This is a swashbuckling thrill ride riddled with moments that make the characters alive.

A remarkable adventure by award-winning author Matthew J. Kirby brings a fantastical American West filled with secrets and spies and terrifying creatures to vivid life.
In this extraordinary adventure story, Billy Bartram, his father, and a secret society of philosophers and scientists venture into the American wilderness in search of the lost people of the Welsh Prince Madoc, seeking aid in the coming war against the French. Traveling in a flying airship, the members of the expedition find their lives frequently endangered in the untamed American West by terrifying creatures, a party of French soldiers hot on their trail, and the constant threat of traitors and spies. Billy will face hazards greater than he can ever imagine as, together with his father, he gets caught up in the fight for the biggest prize of all: America.
