The havoc wrought by the time travel of the Fitzgerald siblings continues in this third book in the Time Benders series. Mary has been dealt a terrible blow. She discovers her fate as a result of Mr. Brewster's and Thomas' trip forward in time. She makes a drastic and emotionally-charged decision to break with Ken. The protection of her secret comes close to breaking the bonds between Ken and his siblings, until he overhears a conversation and learns the truth. All the while, Kim is growing up, and impatiently waiting for her chance to make a mark on the world as her older siblings have done. She convinces Joe and Becky to join her on a humanitarian mission to Philadelphia in 1853. There to assist the abolitionists and the underground railroad, they find themselves trapped for many days in 1853 when Joe gets too close to a fugitive slave trial and winds up in jail! The trip explodes when Mr. Brewster alerts the others to the missing Joe, Becky and Kim. Deb makes a perilous choice to reveal their secrets to Uncle Darrick. All of this time travel is cause for multiple corrective trips in the machine, when Joe's cell mate turns out to be a co-conspirator in the Lincoln assassination and Uncle Darrick uses the machine to mend his relationship with his now dead father. Ken and Ryan travel back to keep Joe from conversations with his cellmate that dramatically change the course of history and Mr. Brewster must travel to stop Uncle Darrick from ruining his relationship with Alicia. When the dust settles, and the group gathers, they make several profound decisions about their fate, their memories, and their time travel and discover they have travelled a long way, and learned much on their long road home. These now familiar characters will warm your hearts and restore your faith!
