Biology of Love by Timothy Perper: Essentially a biosocial textbook with much more than pick up info. The info thats in here though, I have literally not found anywhere else. 5/5 must read

Undercover Sex Signals by Leil Lowndes. This book is flat out necessary for most guys, even here on seddit. 4/5 easy read and free pdf online.

How to Make Anyone Fall in Love with You by Leil Lowndes. This is for men and women, but it lives up to its name far more than most PUA books. 4/5 easy read free online.

Swoon: Great Seducers and Why Women Love Them by Betsy Prioleau. 3/5 A decent read, especially if you enjoy the Art of Seduction.

The common theme is these books are fact or history based books. Mystery Method works from concepts in the above books, Mark Manson's Models too. Infact the valuable part of all pickup books isnt the gimmicks, but most likely the behavioral patterns outlined in Perper's research which we all unconsciously follow.
