I'd read a couple other books by this author and liked them fine ... this was about the same. It was free, included in my KindleUnlimited subscription, text and audio. I mostly went with the audio, but was glad to have the kindle copy for some reference. 

This had a mix of past and present tense, mostly present tense for the current storyline, past for memories. First person, all from the POV of our Heartbreak Bunny, Billie. Simple/chronological chapters, no headers.  Lots of dialog without the "he says/she says" (the narrator did a good job keeping it straight with different voices, I think I might have had a few moments reading myself thinking "who is talking?")

I don't know how much I'll really remember the story ... even waiting a few days to write the review and I'm having to skim over the text to see what I remember. Dressing up as a bunny was memorable (but not really tied to the title - that's her catch phrase and name of her company). A little different in that our MC is over 60, and the discussion of "love/sex" in the older years was a bit interesting, not the traditional 20-something love story. Nothing really explicit. A little proFanity (x3). 

A strange pronunciation of Kiefer ... Kay-Fear ???
Word - cacophony. Not one I'd generally be tracking, but someone in a FB group mentioned seeing it in so many reads, and there it was ;)  It did have smirk and scowl.
