We meet Aubrey in the Snow & Winter series. Aubrey is a great friend to Sebastian and is located in the sunny location of Florida, providing a nice backdrop to a well-told and hilarious murder mystery. Aubrey is the property manager of Smith Family Historical Home. He's ready for a bit of downtime with Jun Tanaka, FBI agent, and partner to Aubrey's ex-boyfriend. There's a skeleton in one of the closets and this sets off a series of events. You don't have a "Sebastian" level of interference from Aubrey, but you do get to see the investigation play out... with some instigation from Aubrey.
An interesting aspect of this story was Aubrey's narcolepsy. Like with Sebastian's colorblindness, you get details of the condition and it plays a small part in the storyline. It doesn't overwhelm the story, but it was interesting to get a day-to-day rundown of what it would be like to have narcolepsy. Aubrey and Jun were perfect for each other. They balance each other very well. Aubrey had "in your face" style of humor, whereas Jun's was nice and subtle. While this could be read as a standalone, you can read it along with Sebastian's series. (Read it after "The Mystery of the Curiosities". This takes place directly after book 2). I hope this is the start to a series, it's that good!
