So, in PowerPoint, go to File > Share and choose Embed. Click the Generate button and then choose the dimensions of the embed. Copy the embed code that is provided.
In Book Creator, from the + button go to More > Embed and paste the code. Change the title and the presentation is embedded. Now when you switch to Read Mode and click on the presentation, it will open up in the book like this:
