* FirstInstallmentWins: This book has sold 87 million copies, has been translated into 44 languages, and has never been out of print. The sequels weren't so lucky.
* BadassDecay: In ''She'', Ayesha is an outright tyrannical [[MurderTheHypotenuse hypotenuse-murdering]] villain (though [[EvilIsSexy very attractive with it]]). Over the course of subsequent books she is softened, excuses are supplied for her excesses, and she turns out to be Leo Vincey's true soulmate.
