Mythmatched Timeline
The books in the Mythmatched universe (both the traditional romances and the Quest mysteries) take place in just over a single story year. Mostly, the story chronology follows publication date, but there are a couple of little overlaps. Here’s the timeline, in case you’d like to read them in order.
Because the series is rooted in Celtic mythology, I’m using Celtic quarter days and cross-quarter days as calendar signposts here. The dates are approximate, however, since all the books span multiple days (and sometimes longer).
–E

Summer Solstice
Cutie and the Beast
Alun and David

Autumnal Equinox
The Druid Next Door
Mal and Bryce

Samhain
Bad Boy’s Bard
Gareth and Niall
Winter Solstice (concurrent)
Single White Incubus
Ted and Quentin
Note: Single White Incubus begins a day earlier than Vampire With Benefits and ends an unspecified number of days earlier as well, but both books essentially cover the same time period.
Winter Solstice (concurrent)
Vampire With Benefits
Cas and Rusty
Note: Vampire With Benefits starts a day later than Single White Incubus (on the same day as Howling on Hold). It ends a little later than Single White Incubus, but earlier than Howling on Hold.

Winter Solstice
Second First Date
Cas and Rusty
Second First Date is a free, subscriber-only story that’s essentially a seven-chapter epilogue to Vampire With Benefits. I wrote it for all my readers who wanted to know what happened after “The End.”
Imbolc
Demon on the Down-Low
Zeke and Hamish
Note: The last scene in Demon on the Down-Low actually occurs on the vernal equinox itself, after the end of Howling on Hold, but there’s a significant time jump beforehand, and most of the book takes place closer to Imbolc.
Vernal Equinox
Howling on Hold
Chase and Tanner
Note: Howling on Hold actually begins on the same day as Vampire With Benefits. (Look at the scene in the Bullpen, the Portland shifter bar, in each book for sightings of familiar characters!) However, the majority of the book takes place closer to the equinox.
Vernal Equinox
Rusty’s Really Bad Day
Cas and Rusty (mostly Rusty)
Note: Rusty’s Really Bad Day is a “sidecar” or companion story–closely linked to Vampire With Benefits as well as several other books in the Mythmatched world. It’s set during the second week in March—between the end of Howling on Hold (which takes place on Cas and Rusty’s wedding day) and the last chapter of Demon on the Down-Low (which occurs on the vernal equinox, Mal and Bryce’s handfasting day), and is not intended to stand alone.
Beltane
Possession in Session
Wash and AJ
Summer Solstice
Witch Under Wraps
Ky and Ewan
(Sharp-eyed readers will spot Ky’s first appearance back in Vampire With Benefits. He shows up in Possession in Session, his brother Wash’s story, as well.)

Pre-Autumnal Equinox
Five Dead Herrings
Matt and Lachlan #1
(The Quest books don’t align quite as neatly with the quarter days, since they’re separated by weeks, not months.)

Post-Autumnal Equinox
The Hound of the Burgervilles
Matt and Lachlan #2

Pre-Samhain
The Lady Under the Lake
Matt and Lachlan #3

Pre-Samhain
Cursed is the Worst
Taj and Kiran
(Cursed is the Worst occurs during the events of The Lady Under the Lake, but Zeke, our favorite demon office manager, is the only character who appears in both.)

Pre-Samhain
At Odds with the Gods
Finn and Gany
(A Mythmatched/Purgatory Playhouse crossover; takes place concurrently with Cursed is the Worst.)

Post-Samhain
Death on Denial
Matt and Lachlan #4

Post-winter Solstice
The Skinny on Djinni
Hector and Rafi

Pre-Summer Solstice
Assassin by Accident
Seb and Nevan

Pre-Summer Solstice
First Flight
Seb and Nevan
First Flight is a Mythmatched “sidecar” or companion story. It takes place between chapter 33 and the epilogue of Assassin by Accident.
