Peter is a Harvard graduate with a degree in biochemistry. He has run a marathon and gone rock climbing during an earthquake-though not on the same day. In his spare time, he likes to eat chocolate. Seriously, he loves chocolate. Throwback (HarperCollins) is the first installment in an electrifying new trilogy about a boy who discovers that he alone may be able to alter the course of history. Corey Fletcher has an active imagination. He sees things no one else does. Cracks jokes no one else gets. And goes places few would ever dare go. Like the past. All he needs is a metal artifact from a point in time, and Corey can go there. Although hundreds of time travelers live in secret throughout the world, including Corey’s own grandfather, none has the ability to change past events. But when Corey accidentally saves a life while time traveling, he realizes that he is the first-ever “Throwback,” with the power to alter life as we know it. Which means his own life is now in all sorts of danger.
