Countdown to Launch
Dear readers,
Today, we are two weeks away from Hot Wax pub day. It’s an exciting but incredibly busy time; if you’ve following me on social media, you’ve probably seen a lot of event announcements, some early reviews, and even some early swag. But I wanted to go ahead and send this reminder for those of you who are less chronically online.
The Hot Wax book tour starts one night early at the Strand in New York City; we’ll be in the rare books room on the second floor, and it’s worth the ...

HOT WAX Ireland Event
Great news for my pals in Ireland who have been patiently waiting (for years!) for an event in their neck of the woods: we’re bringing the Hot Wax world tour to Dublin on October 22nd.

You can find tickets and more information here. Hope to see you there!

HOT WAX US Tour Dates
Calling all road dogs!
The US Hot Wax tour is live. I’m so excited we’ll be able to bring this book to so many cities this fall, and it’s going to be an absolute blast. We’re working hard behind the scenes to bring you treats, tunes, tour merch, and so much more. It’s a really weird time to be promoting a book but now more than ever is a moment to fight for the arts and celebrate–loudly–everything that makes life colorful, vibrant, and worth living. I can’t wait to meet you all.

HOT WAX Pre-orders and UK Tour Dates
It’s been too quiet here for a little too long. But the good news is we’ve got good news worth sharing, so I’ll get right to the point. Hot Wax launch is just about three months away. It’s wild how fast this time has flown, but now that we’re really in the home stretch we can finally share some things with you.
The first is NetGalley requests and pre-order links. If you’re a NetGalley member, you can request the US edition of the book here and the UK edition here. Our galleys–both print and ...

HOT WAX cover art
I won’t waste your time. It’s here. It’s hot. It’s big. It’s loud. I’m in love with it.

There are so many things I could say about this cover. A lot of care went into the design, and it looks absolutely delicious.
My editor, T., wanted this to feel like “ a big book.” We needed something high-contrast and eye-catching that would demand a reader’s attention as soon as they walked into the bookstore. Because the title is still about this book, and becaus...

US Tour Dates and Graveyard News
It’s been a busy couple of weeks behind the scenes for the Rio team but we have some great news. Graveyard Shift is an IndieNext pick for October and one of Amazon’s Best Mysteries & Thrillers of the month!

It’s so exciting to see this little book getting so much love from the bookselling community. We can’t wait to share it with readers, which brings me to our next piece of good news: we finally have our US tour finalized. You can find all the dates and relevant links on the Events page,...

UK Tour Dates
Delighted to be returning to the UK this fall for some Graveyard Shift events. I hope you’ll come out and get a book signed–it promises to be a spooky good time. You can grab tickets here (and grab them fast, because space is limited).

New US Edition of IWWV
Excited to share the cover art for the new US paperback edition of If We Were Villains. It’ll be available on the same day as Graveyard Shift: September 24 of this year. It’s been a long time in the works, but we wanted to update the original black-and-white paperback, which will be discontinued once the new version hits the shelves–with those sexy red spredges and everything. If you want one of the originals and haven’t grabbed it yet, now would be a good time! And if you’re as enamored with th...

Upcoming Events
Checking in with a quick update from the first stop of my eight-week conference/wedding/speaking/research tour. I’m in Chicago at the moment for the Renaissance Society of America Conference, and really looking forward to continuing the scholastic conversation at Arizona State University next month. I’ll be making a few classroom appearances as well as doing a larger event open to the public on April 17, so if you’re in the Phoenix/Tempe area I hope you’ll come out and join us. This will be a ra...

GRAVEYARD SHIFT cover reveal
Short post today as I’m on All the Deadlines, but we’re excited to finally show you the cover art for Graveyard Shift, along with an official release date. Mark your calendars for September 24, 2024.

Don’t forget you can already pre-order the book if you’re in the U.S., and pre-orders are a huge help to bookstores, publishers, and authors because they take some of the guesswork out of the printing process. If you’re outside the United States, don’t worry–we’re working on getting foreig...
