The Action Heroine's Handbook by Jennifer Worick and Joe Borgenicht
From the back cover:
"For every woman who wants to be as tough as Lara Croft, as nimble as the Bionic Woman, and as babe-a-licious as Charlie's Angels, The Action Heroine's Handbook shows you the essential skills you'll need to conquer the bad guys and save the day without breaking a sweat.
"Find out how real action heroines do it, directly from a host of experts, including stuntwomen, jujitsu instructors, helicopter pilots, detectives, forensic psychologists, survivalists, primatologists, and many others."
Do you write romances or mysteries or urban fantasy with kick-ass heroines? (Yes, we're all tired of that phrase, but it is an understood keyword for a certain type of female protagonist.) If you do, then you need this book as part of your research library. Where else can you find instructions on how to go undercover as a prostitute in a brothel, recognize the undead, profile a serial killer, be a Mob wife, choke a man with your bare thighs, fake your own death, and outrun a fireball? Really, step by step instructions on this and much more.
The book sections are:
~ Tough Chick Skills (including How to Win a High-Speed Chase in High Heels and a Bustier)
~ Beauty Skills (like How to Seduce the Enemy)
~ Brain Skills (How to Investigate Your Spouse/Lover)
~ Brawn Skills (How to Subdue Your Opponent With a Whip)
~ Escape Skills (How to Escape When Kidnapped)
The appendices list what your girl should be carrying in her purse and how she should style her hair.
So if you've got an "action heroine" in your book, this handy-dandy reference can help you make your story a lot more plausible and realistic.
