The Unknown Spy (Ring of Five)
by Eoin McNamee

3 out of 5 stars

Danny attends Wilsons Academy, a school for spies in another Lower World. They work to stop an army of Cherbs from invading the Upper World of humans. Danny makes friends among the spy cadets of the academy. Les is a thief with wings. Dixie can teleport anywhere she can see her way through. And Vandra has special healing powers. Together they learn all the skills they need to spy on the evil Ring of Five who control the Cherb army, but the most essential skill for any spy is the art of betrayal.

In this second book of the series, Danny is entrusted with a special mission in the Upper World to find the Treaty Stone that stops the Cherb armies from invading the world of humans. He must protect the Treaty Stone at all costs against the Cherb spies who would try to destroy it. Along the way, he is tempted to betray his friends, and he learns that he may have a special power that is entirely unique.

I liked this book pretty well. I loved the weird spy classes and the fun camaraderie between Danny and his friends. The world building is really imaginative and I liked all the weird characters.

I liked the writing style, and the plot moves along fairly quickly. There is a lot of intrigue and mystery as you would expect for this type of story. It was interesting and I loved seeing how Danny gradually learns to trust his friends more and more.
