[NOTE: I began writing this book in 2011 when I was 13 years old. There are many grammatical errors, cringe-worthy moments, and plot inconsistencies. Obviously, my writing has improved immensely since 2011, so please feel free to check out any of my more recent works instead. This book is not representative of my present-day writing abilities. I would prefer to delete this entirely (and its sequel), but there have been many readers who have expressed their love and appreciation for this book despite its flaws. Regardless, thank you all for your support with the Detention series over the past few years. I love and appreciate each and every one of you.]
