For those who prefer text:

Gillian Urswick and Kit Marlowe (short stories): The Kit Marlowe shorts fill in some background on the Silver Circle, the main magical organization mentioned in the two series, and provide information on a cross-over character, Elizabethan bad boy Christopher (Kit) Marlowe. They can be read at any time, before, during or after the main series. So far they include "The Gauntlet" and "The Queen's Witch," both available for free on this website or at Smashwords.com.

The Cassie Palmer books (main series): The time traveling, ghost-whispering, crazy blond who started it all currently has eight books in her series: Touch the Dark, Claimed by Shadow, Embrace the Night, Curse the Dawn, Hunt the Moon, Tempt the Stars, Reap the Wind, and Ride the Storm (2016). They follow each other in chronological order (or as much as possible with Cassie's tendency to time shift.) They are best read in order, but stand alone reasonably well. They tie in with and overlap the Dorina Basarab series, which is set in the same universe.

Extra free stories for the Cassie Palmer series: These are available on the web site and (most) can also be found at Smashwords.com. "Updating Pritkin" is a tongue in cheek glimpse into life around Dante's casino and can be read at any time. "Shitty Beer" is a John Pritkin short set during Claimed by Shadow. "A Family Affair" and "Shadowland," are Pritkin shorts set between Curse the Dawn and Hunt the Moon. "The House at Cobb End," deals with Pritkin's life before the beginning of the Cassie series, but to avoid spoilers, it should also be read after Curse the DawnThe Day of the Dead," features Tomas from Touch the Dark and Claimed by Shadow, and should be read after those books.

The Dorina Basarab books (main series): These books tell the story of the dhampir daughter of Mircea Basarab, a major figure in the Cassie Palmer series. A number of crossover characters and plotlines connect the two series, which I have always viewed as one. So far, there are four novels about Dory: Midnight’s Daughter, Death’s Mistress, Fury’s Kiss and Shadow's Bane. The first Dorina (Midnight's Daughter) can be read after the second Cassie (Claimed by Shadow) because it concludes the storyline begun in that book. Or, if you wish to read chronologically, it can be read after Embrace the Night, the third Cassie, which it overlaps. The novella, "Buying Trouble," (available in the On the Prowl anthology or by itself as an ebook) should be read before the start of the Dorina series, as it sets up some of the conflicts of Midnight's Daughter. It is not necessary to understand or enjoy the novel, however.

Extra free stories for the Dorina Basarab series: The short "In Vino Veritas" from the Chicks Kick Butt anthology, the novella "Zombie's Bite", and the novella "Lover's Knot" can be found for free on this web site and at Smashwords.com. 

Masks: This is a Mircea Basarab full-length novel set in fifteenth century Venice. It details his early life as a vampire and gives some insight into Dorina's. 

Lia de Croissets (short stories): The Lia de Croisset's short stories can be read at any time and as an addition to either series. They are set in Las Vegas, like the Cassie books, but deal with the war mage corps and Were politics. They are slightly ahead of the other two storylines for now, but care has been taken to avoid spoilers.
