I am currently reading the first book in the Time Riders series by Alex Scarrow and it is proving to be a promising choice for the younger male reader. Our heroes are pulled out of the future right at the point of their deaths to travel back in time and act as guardians of history. Time travel has been outlawed, but this does not keep a few who think they can create a better history from going back and trying to change things. Our heroes are charged with trying to prevent those changes and not create any of their own.
Another time traveling pair of heroes are found in The Reluctant Assassin by Eoin Colfer. This is the first book in the W.A.R.P. series. W.A.R.P. stands for the Witness Anonymous Relocation Program. This is a Witness Relocation Program with a twist. Witnesses are hidden back in history and are meant to be brought back at the appropriate time to testify, but as in every good story, something goes wrong.
If you like historical fiction, you might like The Boy Who Dared by Susan Campbell Bartoletti. This novel is based on the true story of a young man who stood up for what he believed. Written during the time of Hitler's rise to power, this novel will make the reader think about propaganda's power over people and how something that appears to be good can turn into something evil.
One of my favorite authors for boys is Rick Yancey. The Extraordinary Adventures of Alfred Kropp is the first in a series that keeps the reader on the edge of their seat. Alfred is a clumsy young man that is trying to find where he fits in the world. What he discovers is that he comes from a very famous lineage and is entrusted with a very special job. This story is action from start to finish with sword fights, fast cars, and much more.
Other suggested books include; Leviathan by Scott Westerfeld, the Alex Rider series by Anthony Horowitz, Crater by Homer Hickam, Holes by Carl Hiaasen, The Joshua Files by M.G. Harris, Dormia by Jake Halpern, the Young James Bond series by Charlie Higson, and The Last Thing I Remember by Andrew Klavan.
