This book is on sale today for $0.99. Seems like a good book but the Table of Contents is messed up. Hopefully someone from Vyrso will see this post and take a look at it.
If you want me to elaborate, the book has 9 Sections with 90 subsections. The ToC only shows general automated titles like: Cover, Titlepage, Halftitlepage, Section1, etc
I've had this issue with the recently released Walvoord books but I haven't seen any progress on that either so I'll attempt to shoot CS an email later today
