I usually do not like reading science fiction books because they seem to have the same stereotypical plot, however, I definitely love this book. It kept me captivated with its twists and turns and unexpected plot lines. I like how the main character, Thomas, is likable because it's hard to read a book when the main character is irritating. The epilogue made me want to read the rest of the trilogy to know why Teresa wrote "Wicked is evil" on her arm. The pieces that were scattered throughout the plot connecting, in the end, was enjoyable to read. I definitely recommend this book.
