Here's how it works ~
Step 1: You PM me a link to your book.
Step 2: I'm not allowed to view the actual writing, only the synopsis and the cover.
Step 3: I recreate the cover in MS paint (with creative liberties).
Step 4: I come up with the subtitle.
Step 5: I expand upon the synopsis, and write you how I (specifically) think your book should end.
Step 6: Based on my impression of you (or maybe literally nothing at all), I write a bio for you.
And that's that! I'm not requiring any form of "payment", just keep in mind I may not be able to finish your request immediately.
But definitely feel free to recommend this book to your friends!
Do it.
