Lincoln & Adeline: They both begin their journey in their story Path of Destruction. Then they make appearances in If We Could Go Back, Inappropriately Yours, Uncomplicated Choices, Power Play, Stranded, and Out for the Holidays. Adeline appears later in Deserted too.
Dominic & Adrian: Start their journey in their story Home, after which Adrian makes a brief appearance in Inappropriately Yours, then both pop up in Uncomplicated Choices, Out, Out for the Holidays, and Sleepless. Lastly, Dominic shows up in Deserted.
William & Kelly: William appears briefly in If We Could Go Back, then gets his own story with Kelly in When Forever Ended. Brief appearances/mentions in Inappropriately Yours and Out for the Holidays, and then as significant secondary characters in Fall by Winter.
Isla & Jack: Jack is mentioned for the first time in When Forever Ended, but he doesn’t appear until his story, Inappropriately Yours, alongside Isla. After that, they appear in Stranded, are mentioned in Deserted, before they play significant secondary roles in Dirty Chef.
Chloe & Aiden: Start their journey in their story Inappropriately Yours, and then Aiden appears in Power Play before they both pop up in the Auctioned Series, namely Stranded and Deserted.
Casey & Ellis: Casey is Lincoln’s cellmate in Path of Destruction, where Ellis is just mentioned, and then they appear as secondary characters in If We Could Go Back, after which they get their own story in Uncomplicated Choices. After that, they appear very briefly in Three Dirty Harts, and more in Power Play, Out for the Holidays, and Sleepless.
Zach & Henry: Start their journey in their story Out, followed by the holiday sequel Out for the Holidays. Then they appear as secondary characters in Sleepless.

Gray & Darius: Gray’s first appearance is in Inappropriately Yours since he’s Chloe’s son. Darius shows up in Uncomplicated Choices. Then both Gray and Darius appear in Power Play, though separately because they don’t know each other yet, before they start their own series with Auctioned—then Stranded, Deserted, Played, and Finished. For a flashback to several years of Darius’s past, check out Her All Along, which chronologically takes place long before any other book, but for Darius’s sake, it’s best enjoyed once you’ve read Auctioned, Stranded, and Deserted.
Adam & Alessia: Adam first appears in When Forever Ended, then they both appear in Inappropriately Yours and Power Play, before they get their own story Dirty Chef. Adam’s briefly mentioned in Fall by Winter too.
Avery & Elise: Chronologically, Elise and Avery start their journey in their story, Her All Along, but if you read the CCU books by Author’s Choice, she makes her first appearance in Stranded. (As most books in the CCU, Her All Along is a standalone novel, but if you’re in it to follow the secondary characters as well, read Auctioned, Stranded, and Deserted before you dive into Her All Along. Simply because Darius in the Auctioned Series has a significant part in Her All Along, and the book is packed with insider jokes on his expense—which otherwise goes completely unnoticed.)
Bennett & Kieran: Start their journey in their story If We Could Go Back. Bennett makes a brief appearance at the end of Three Dirty Harts, and the couple is mentioned as Jess and Jaylin’s parents in Fall by Winter. Bennett also pops up quickly in Just Sign Here.
Edward & Peyton: Both appear for the first time in their own story, Just Sign Here. It’s also the only book in which they appear, so far.
Andrew/Belle/Jace: All three appear for the first time in their own story, Three Dirty Harts. It’s also the only book in which they appear, so far.
Much more to come as new characters are born and secondary characters get their own stories told!
Friends of Camassia
Ryan/Angel/Greg: Ryan, Angel, and Greg share a story in Touch: The Complete Series, a BDSM series unrelated to Camassia. But with Ryan linked to Darius (they’re brothers,) it was only a matter of time before Ryan became a reader’s favorite through the Auctioned Series. Since then, Ryan’s also appeared in Her All Along, and there’s more to come for this kinky triad. More info later.
