Margaret's father has been sentenced to death for a murder he did not commit. As he is taken from the court room, he makes Margaret repeat the "forswearing" a promise all the people in her family make to not time travel, although they have the power to do so. After conferring with her best friend Charlie, and his grandfather, Joshua, Margaret decides to go back in time, even though by doing so she is risking everything she cares about in the present. She travels to 1938 to try to change the early life of the vindictive and corrupt judge who convicted her father.
This is perhaps my favorite book I have read this year. It had a very complicated and sophisticated plot, and fully realized characters. As the different characters grapple with the ethics of time travel, De Los Santos packs in a ton of wisdom but only in one small place did it start to feel a little preachy. On top of all that, the writing is really good. The book kind of felt like Tuck Everlasting and perhaps like Tuck Everlasting, it will mostly appeal to adults. (279 p.)
