While it's natural to assume that the book would be about becoming a teen mom, Kailyn tweeted that it's mostly about "living with an addict and absent father resulting in where I am now."
Since that tweet back in March, Kailyn has been pretty quiet about the project, although she was probably pretty busy with her wedding and second pregnancy.
Now, some new details about the book have been released and it sounds like she's still been plugging along, despite her busy schedule.
Over the weekend, Kail tweeted that the book is "coming soon," admitting that it's been a "long process."
The book will be entitled Pride Over Pity, which matches a tattoo Kailyn has near her collarbone.
"People won't expect what's coming," she teased, adding that she has dreams of it becoming a NY Times best seller.
With all that she's already shared on the show, we can't imagine that there would be too many more surprises, but we're still anxious to get our hands on a copy so we can see what she has to say!
