Made Mine is a co author with Sloane Kennedy that is best read after Grounding Griffin (Book 4, Made Marian series by Lucy Lennox) and Unexpected (Book 10, The from the Protectors series by Sloane Kennedy).
Hay is a short novella about Hayworth Buchanan who we meet in Moving Maverick on Rabbit Island. This book should be read after Moving Maverick but is considered. a standalone.
A Very Marian Christmas takes place after Delivering Dante. The shorts and mixtapes are just collections of short stories or bonus scenes. I don’t believe they are necessary to the stories but are nice sweet fluff to read.
