The break-up guide, which started as an app released in March last year, will now be available in paper form.
The Wrong Girl author previously revealed that the idea started as a book, but decided to create the digital version first, because "the broken-hearted tend to live on their phone, and also do silly things on that phone, so having a break-up coach in their pocket made sense to me."
Due to popular demand Foster-Blake decided to finally turn it into a book, making it her seventh release.
Break-Up Boss goes on sale in April.
