Mr. Hornsby and the Time Traveling Classroom: Book 1: Secrets of Pierce Journal

Teaching was never supposed to be like this! When the insecure, history-obsessed, rookie-substitute teacher Mr. Hornsby steps into a classroom at Upper Kakapo Middle School and is transported back in time, a brand-new series for middle schoolers is born. In Book 1: Secrets of the Pierce Journal, Mr. Hornsby learns that two of his new students from the past are actually future presidents and American history is in jeopardy. If he can't discover the origins of his time-traveling powers in time and help his new students, the United States will never be the same. The clues to it all lie inside a centuries-old journal, which will unveil the truth behind America's greatest mystery and an enemy he's not sure can be stopped.
