I'm an audio person (ask me how I suffered when my kid needed to borrow my spare set of earbuds for a long time. Only one set of earbuds - not counting my noise-canceling headphones, or the ones embedded in a headband. And then I lost one of the buds in my only remaining pair!)
(Now you know what's on my birthday wish list.)
Anyway, in addition to all the audiobooks, I'm a huge fan of podcasts. The list of ones I subscribe to is ... unreasonably long, so I won't get into all of it. But there are a few in my rotation that are hosted or co-hosted by romance authors, and while they cover various topics, they all touch on the topic of writing.
Smart Podcast Trashy Books is primarily hosted by blogger and author Sarah Wendell. This is the OG romance podcast, and in particular I love Sarah's interviews of other authors. when any number of interesting ideas and tidbits about the writing life.
Dear Romance Writer is co-hosted by romance authors Xio Axlerod, Roan Parrish, and Avery Flynn, with fairly regular guest hosts who are also romance authors, They offer advice column discussions at the top of the podcast, and then switch to talking about writing issues connected to the advice.
My Imaginary Friends is author L Penelope's podcast entirely about her writing journey. She talks about where she's at with her ongoing work, often discussing tools she uses, info she gleaned from workshops or discussion with other authors, and the publishing process.
Fated Mates is cohosted by author Sarah MacLean and critic/reader/editor Jen Prokop. They discuss romance novels they love, and the history of the genre, often with other guest authors. While it's not a 'here's how to be an author' podcast, the discussions often touch on craft and publishing in fun and informative ways.
So that's (in last-is-best order) my current top list of romance author podcasts. If you've got others to rec for me, I'd love to hear about them in the comments!
