Such a clever story! The main character is a 19-year-old male and deals with a coming-of-age theme, so I suppose the genre is YA. However, I'm a middle-aged female and was captivated by the details.
Franklin Brock Sinclair, 19, bonks his head in Texas in the year 2029 and awakens in Philadelphia in the year 1787. He is in a hospital that, albeit advanced for its time, it is primitive by Brock's standards. He barely escapes with his life once he awakens from his coma state and starts spouting "nonsense" about being from the future!
Brock is befriended by Isaac, an intern from the hospital studying to become a doctor, and Isaac's family. Without them (and later Ben Franklin, et al.), Brock would have ended up back in the basement portion of the hospital where the mental patients were housed.
Trinkets of interest from the beginning of the book include illicit drug activity and "blacking out" in 2029 followed by waking up with a lump on the head in 1787. A tattoo acquired from the future comes into play, and if you know your King James Bible verses, you can imagine what kind of trouble that might get you into! There's a possibility of romance...maybe! Gracious, the smells of 1787 come leaping off the page, and I felt Brock's pain as he wished for something akin to hand sanitizer and a toothbrush.
I would not recommend this book for a middle school library because of the amount of casual cussing by Brock. But, I am middle-aged, and times do change. It should be fine for a high school library though as the cuss words are fairly tame by my account.
I loved the relationships that Brock formed in 1787 and his earnest desire to return to his parents, in spite of their not-so-perfect relationship. The Jamison family was especially important to this story, so pay attention!
