"Maybe Not" is a novella by bestselling author Colleen Hoover, published in 2014. The book is a spin-off of the author's earlier novel "Maybe Someday," and follows the story of Warren, one of the supporting characters in the original book.

The novella tells the story of Warren, a confident and charming guy who has no problem getting women. However, when he meets his new roommate, Bridgette, he finds himself struggling to get her attention. Bridgette is smart, independent, and not easily impressed by Warren's usual tactics. The two develop a love-hate relationship as they try to navigate living together and their growing attraction to each other.

As Warren and Bridgette spend more time together, they start to open up about their pasts and the reasons behind their guarded personalities. Warren, who is usually carefree and unbothered by anything, reveals a darker side of himself, while Bridgette shares the pain and trauma from her childhood.

Despite their differences, Warren and Bridgette find comfort in each other's company, and their relationship begins to evolve into something more. However, their budding romance is threatened by Bridgette's past and Warren's fear of commitment.

"Maybe Not" is a light-hearted and entertaining read, with Hoover's signature humor and romance. The novella can be read as a standalone, but readers familiar with "Maybe Someday" will enjoy the additional depth and backstory provided for Warren's character.

In summary, "Maybe Not" is a fun and engaging novella that explores the complexities of relationships and the power of vulnerability and trust.
