Billionaire Collection Books in Order

The Billionaire Collection books spin out of the larger billionaire universe into a set of standalones that are loosely linked by friendship and family ties rather than one continuous plot. Each story focuses on a different self made billionaire and the ordinary woman who manages to knock him completely off script.

The Billionaire Boss Next Door pairs Trent Turner, a driven developer and hotel heir, with a quirky designer tasked with bringing his new New Orleans property to life. Their professional relationship starts off on the wrong foot, and things get even more complicated when she realizes he is also her new next door neighbor. Long hours, thin walls, and clashing visions for the property slowly turn animosity into something much more intimate.

In My Brother's Billionaire Best Friend, small town book lover Mabel “Maybe” Willis accidentally sends a string of wildly explicit texts to the wrong contact. Instead of a throwaway number, they land in the inbox of Milo Ives, her childhood crush and her brother’s now billionaire best friend. The book leans into mortification, second chances, and the slow delight of someone finally seeing you as an adult.

The Billionaire Book Club follows a wealthy hero who decides that reading romance novels might be the key to understanding women and fixing his dating life. What starts as a joke book club with his friends turns serious when a certain shy, sharp witted woman refuses to treat him like anything special. The story plays with meta humor about tropes and what people expect from romance itself.

The Billionaire's Forbidden Little Sister delivers on exactly what the title promises. Theo Cruz, a man tied to a powerful New York business empire, falls for a woman he meets overseas, only to discover that she is the younger sister of one of his loudest, most opinionated billionaire friends. Bro code, family loyalty, and the fear of blowing up a long standing friendship all clash with the impossible to ignore pull between them.

Across the series you will recognize cameos from the original Billionaire Bad Boys and their partners, plus a web of connections to other books. Read in order, the Billionaire Collection feels like a set of companion stories that fill in the edges of an already busy social circle. Read individually, each one still stands as a full romcom with its own arc and payoff.

If what you love most in Max Monroe’s catalog are the outrageous text threads, mortifying meet cutes, and over the top best friends, this collection gives you all of that in four focused, standalone doses.
