JD Robb’s In Death series is a go-to read for me. I’ve not missed any and own most of the series. Forgotten in Death is number 53 and Nora Roberts’s creations – Lieutenant Eve Dallas and her mega-rich hubby Roarke are still going strong.
I hate the ‘guilty pleasure’ phrase as it implies there’s something wrong with what you’re enjoying but (as I’ve said before) these are akin to a comfort read. There’s a predictability – or rather reliability – about the characters and their behaviour as well as the overall story arc, but Robb / Roberts always offers readers a whodunnit that’s a bit different, though I’m not sure how she manages after so many.
