Drove me to delurk for this one, as you see. I'm still waiting to see if the Kerry Greenwood books go on special directly at PPP, but I used to buy the physical books directly from Australia or on eBay while she was between US publishers, otherwise I'd already have scarfed the lot.
I'll note that the first few Phyrne Fisher books (Cocaine Blues, Flying Too High, Murder on the Ballarat Train) are fairly short, so if these sound like maybes for anyone, it could be worth prioritizing some reading time with Cocaine Blues to see if the books appeal. As with any series, there gets to be a formula as time goes on, but I enjoy the characters in both series and their lives in Australia. Looking at the list of titles, I could tell you the main action of the first 10 or so, which isn't always true for me that deep in a series, nor do I usually read that deep in a series.
Characteristics: more cozy than gritty, plenty of characters to follow from book to book, amorous intrigue rather than romance in the Phryne Fisher books. I'm sure these aren't for everyone, but in my estimation this is quite a solid author who might be better known if she lived in the US or UK.
