From the publisher:

EN Publishing returns with the second book in the E.N.Arsenal series, this time featuring the sinuous Whip.

This book explores the whip with 23 pages of material about the weapon itself, variants thereof, its history, and those who wield them.

E.N. Arsenal books are "crunch-intensive" - a majority of the PDF is devoted to rules-based material regarding the topic of the book; in this case, the Whip in and variants.

This e-book includes:

Statistics for whips of Tiny through Colossal size.
6 variants of the whip, including four new weaponcrafting materials and a new alchemical item.
Tricks, Tactics and Techniques, including 22 Feats for the wielders of these versatile weapons.
Four prestige classes dedicated to the weapon.
Spells and Psionic Powers
Weapon Enhancements for crafting magical whips and similar weapons.
5 Specific magical and psionic whips.
Ford, God of Whips, a deity of adventurers and rugged manliness, whose symbol is a whip.
