A couple of people on an e-book reading forum that I follow (https://www.mobileread.com) recommended the Kim Harrison Bundle #1, which contains the first four novels in Kim Harrison’s Hollows series. It’s on sale for $3.99 at Kindle US and contains: Dead Witch Walking; The Good, the Bad, and the Undead; Every Which Way But Dead; and A Fistful of Charms. I haven’t personally read anything by this author, but the price is nice, and with a couple of recommendations in a forum I trust, it may be worth a try!
