Posey Banks, a spirited redhead and bookstore clerk, revels in her quaint, quiet life in a sleepy corner of Chicago. A good book usually keeps her content, yet a persistent whisper in her mind tells her something is missing. Perhaps it's spontaneity, passion or even a deeper sense of purpose.
When she meets Noah Jackson, she sees the perfect opportunity to infuse her world with some passionate excitement. What Posey intends as a one-night fling turns into something more when Noah, captivated by her from the moment he saw her, wants to dive deeper. Yet, his chaotic home life and heavy responsibilities threaten to disrupt any sense of normalcy.
As Posey and Noah plunge into an unanticipated romance, she finds that her impulsive leap brings not only the fulfillment she craved, but so much more. Together, they navigate through each other's lives and unearth Noah's traumatic past.
They create an undeniable bond, but even that can't help them prepare for an unforeseen circumstance that could threaten the world as they both now know it.
