Evans only has one standalone novel and one 6-book series.

The standalone: The God Catcher is set in Waterdeep, and is about the daughter of a minor noble who flunks out of wizard school and becomes a rogue, getting caught up in the scheme of some dragons who have found a way to bypass Waterdeep’s mythal and get into the city. It’s a fun ride.

The series is the Brimstone Angels series, about two twin tieflings abandoned at birth and adopted by a curmudgeonly single dad dragonborn. The prologue shows one of the twins accidentally forming a warlock pact with a devil. The biggest ongoing appeals of this series are:

• the nature of an infernal warlock pact and the relation between the warlock and patron
• the experience of a race that internally is absolutely no different to humans (unlike, say, half-orcs, which are canonically actually more likely to be aggressive) but which are perceived as evil
• the politics of the Nine Hells (her patron becomes, especially as the series goes on, a sort of deuteragonist of the series, and we see a lot of internal political dealings, schemes, etc. between different devils of different ranks)

If you’ve read the 5e Player’s Handbook, the quotes that are at the start of the tiefling and dragonborn racial entries both come from this series. The tiefling one is part of the prologue of book 1 (Brimstone Angels) and the dragonborn one is—from memory—from book 5 (Ashes of the Tyrant). The last two books are especially good if you’re interested in dragonborn, or if you like creative fantasy world building in general, because Evans’ background before she got into writing was in anthropology, and the dragonborn culture was not very heavily fleshed out previously, so she had a lot of leeway to do some really cool unique work with them. She’s got a number of articles on her blog about draconic language and dragonborn culture as sort of fun supplemental material. Here’s part 1 of "playing a Dragonborn in the Forgotten Realms". There are also parts 2 and 3 of that series, plus 2 posts of the draconic language.

Book 4 is set in Cormyr, and deals a lot with Cormyrian politics. The closest parallel to which in more popular fantasy that I can think of is Wheel of Time’s Andoran succession crisis

Book 3 was explicitly part of WotC’s The Sundering, a series of books set around the time of the Second Sundering, the in-world explanation for the rule and setting changes between 4th and 5th edition. But Evans was allowed to set all of her remaining books 3–6 during the intermediary period, so book 6 climaxes basically right as the Sundering itself is hitting the world, which plays into her story threads in a major way.

There’s stuff about how Asmodeus came to be a god, how tieflings came to look like they do in 4th and 5th edition, how Azuth returned to life after being presumed dead, and a brief excursion to Toril’s twin plane of Abeir, the magic-less land ruled by dragon tyrants from which the dragonborn escaped.

There’s one other of her blog posts that I’d like to recommend, but I’m putting it down here because it’s a little different. It’s less a lore thing and more something interesting in the writing. Good if you want interesting ideas for narrating at a table, maybe, but mostly interesting if you’re interested in hearing about the writing process. If you’re the kind of person who enjoys seeing the "behind-the-scenes" of movies and the like. It’s this one where she’s talking about how she weaves in a game mechanic into the narrative in a seamless but necessary way. Specifically, how she used a 4e "healing surge" in the first book, a mechanic that was often derided by people who didn’t like 4e because of how unrealistic it was, but which she utilised in a way that was both flawless and entirely necessary (because the character doing it had used an ability that required they be below half health, and then later in the same scene used one that required they be above half health, to be faithful to the game rules).

But yeah, it’s safe to say that I’m a huge fan, and highly recommend her. Unfortunately if audiobook is not an option, book is the only way to get the first Brimstone Angels book, unless you’re lucky enough to have a library with it. But at least when I was buying 6 or so years ago, all the other books in the series were easy to get a hold of.

Oh, I’ll just also add that she’s got two other books set in her own world that I know of. I think at least a third is planned. And next year the classic MMORPG RuneScape is releasing a book set in its world’s past written by her. I’ve not read any of these, but plan to.
