The Sinners of Saint series by L.J. Shen has 5 books and is best read in publication order, starting with Defy (2016).
Start here: Defy (2016) — then read straight through in publication order.

The order the books were released — the default way to read the series.
Sinners of Saint is L. J. Shen's dark, angsty bully-romance series set among a group of wealthy, morally compromised friends in the fictional town of Todos Santos, California. Each book follows one member of the friend group — a group defined by money, cruelty, and buried trauma — as he collides with a heroine who refuses to be steamrolled by him. Expect grovelling anti-heroes, revenge plots, class-conflict tension, and the enemies-to-lovers/bully-romance tropes that made Shen a staple of dark New Adult romance well before BookTok turned her backlist into a fresh wave of bestsellers.
The books are marketed as "interconnected standalones": each has its own complete romance and can technically be read alone, but the friend group's history and running feuds accumulate across the series, and the darkest reveals land hardest if you've read the earlier books first.
Start with Defy (a free/cheap prequel novella introducing the friend group) if you want the full backstory, then read Vicious, Ruckus, Scandalous and Bane in publication order. Defy isn't required — most readers jump straight into Vicious — but it sets up character history that pays off later, especially for Vicious and Ruckus's dynamic. Each numbered book stands alone romantically, but the shared timeline and recurring cast reward reading in order.
Five: the prequel novella Defy, plus Vicious, Ruckus, Scandalous and Bane.
Defy (prequel novella, optional), then Vicious, Ruckus, Scandalous and Bane in publication order.
No — Defy is an optional prequel novella. Vicious is the first full-length novel and works fine as a starting point, though Defy adds backstory for the friend group.
Yes, it's a complete five-book series with no further installments announced as of August 2026.
It shares Shen's fictional Todos Santos, California setting with several of her other books (including the Boston Belles and Vicious brothers extended universe), but Sinners of Saint's five books form their own self-contained story about one friend group.
