St. Martin's Press recently announced that Reinhart's "Swimming Lesson" will hit bookstores next May.
"Swimming Lessons" will explore themes from the 23-year-old actress's own life, such as "the euphoric beginnings of young love, battling anxiety and depression in the face of fame."
A press release described the poems as "bite-sized yet profound," also revealing that they will be accompanied by illustrations.
Reinhart has often displayed her poems on social media, most particularly on her public Tumblr page.
This past August, she shared a "sappy nighttime birthday poem" for the 27th birthday of her "Riverdale" co-star and boyfriend Cole Sprouse, despite rumors that the couple had broken up during the summer after two years of relationship.
"I tried to find a poem / that I could send to you. / Because my words were failing me. / But I searched and found nothing that did you justice. / All of these love poems can't get it right," it reads.
"Swimming Lessons" will mark Reinhart's first venture into literature. The American actress has recently starred in Lorene Scafaria's "Hustlers," alongside Jennifer Lopez, Cardi B, Keke Palmer and Constance Wu.
She will also appear in the upcoming fourth season of "Riverdale," which will premiere on The CW on October 9. It will mark the first season since the death of actor Luke Perry, who played Fred Andrews on the show.
Reinhart notably paid homage to her former cast member in a poem that she shared at the time on her Instagram stories.
"Swimming Lessons" will be published by St. Martin's Press on May 5, 2020, with pre-orders already available.
