Each is hooked to a central character: bounty hunter Stephanie Plum for Evanovich and private eye Kinsey Millhone in Grafton's "alphabet" stories, which started in 1982 with A is for Alibi.
Incidentally, only 7500 of that book were printed initially, so if you have a hard-cover first edition, hang on to it, as the going price collectors will pay is in the region of $12,500.
In Explosive Eighteen, Stephanie Plum continues chasing bond defaulters who don't want to be caught, aided - and frequently hindered - by colleague and former prostitute Lulu, while lusting after two men, Morelli and Ranger. This time, Plum has accidentally acquired a photo that turns out to be a hot property.
Light as a feather and completely escapist, this novel gives no feeling of time moving on, despite the teeniest hint of character development at the end, as Plum contemplates the need to choose between the two men in her life.

V is for Vengeance is the 22nd in the series, so there are just four to go. By 2016, at one a year, Grafton will be in her mid-70s and probably glad to retire, along with Millhone. Evanovich will be 73, so perhaps they could have a dual retirement bash.
