On October 13, 2021, Shannon Messenger via AP News[1] and Instagram[2]revealed a tenth and final book in the Keeper series.

Messenger has said multiple things about this book in the AP news article. “I knew from the very beginning that Sophie’s story was huge. But it was hard to tell at that point how many books it would take to do the Keeper series justice. I’m incredibly grateful that my publisher and fans gave me the freedom, support, and enthusiasm to let the story unfold at its own pace” Messenger writes, “Now I have the space to reveal all of the secrets that readers have been dying to know since book one, and I can’t wait for everyone to read the final conclusion. I promise it will be epic!”

Messenger confirmed that this will be the final book in the series and that it will bring a full conclusion to the series.
