Nina Simon’s New Book Keeps It in the Family: How A Sisters’ Vacation Inspired “My Sister Is Going to Kill Me” (Exclusive)

In a recent discussion, authors Nina and Morgan Simon provided an insightful look into the inspiration behind Nina’s new novel, *My Sister Is Going to Kill Me*, a whodunnit that weaves together elements of mystery and familial relationships. The book, published by William Morrow, hit the shelves on 18 August, taking readers on a thrilling journey alongside sisters Liv and Mandy as they unravel a murder mystery during their holiday at the Grand Canyon.

Drawing heavily from personal experience, Nina revealed that the novel’s foundation was laid during a real-life whitewater rafting trip she shared with her sister, Morgan. The two embarked on this adventure not merely for leisure but as a chance to reconnect away from the stress of their family responsibilities, specifically the ongoing cancer treatments their parents were undergoing at the time.

Reflecting on the significance of their trip, Nina conveyed that it was a turning point in their adult relationship. “It was the first time as adults we went somewhere just the two of us,” she said, reminiscing about the nostalgia of their childhood bond. With both having navigated the complexities of family dynamics, their excursion represented a vital opportunity to reconnect and cherish their sisterly friendship beyond the usual caregiver roles.

Morgan echoed Nina’s sentiment, highlighting the simplicity and beauty of their experience outdoors. “Sleeping under the stars and being immersed in such awe-inspiring scenery allowed us to deepen our bond,” she noted, capturing the essence of their shared adventure. The trip also served as a backdrop for some sisterly tension, where they openly confronted unresolved family issues—a vital growth moment that Morgan now cherishes, despite the initial discomfort.

The novel, shaped by their shared experiences, showcases the intertwining lives of two distinct sisters grappling with their differences while engaging in the fight for survival. Nina explained that she wanted to portray the complexities of sibling relationships, rooting for Liv and Mandy despite their contrasting personalities. “I love writing about profound female relationships; it’s essential to explore that unbreakable bond even when challenges arise,” she expressed.

In a playful exchange, Morgan highlighted how their contrasting traits play into the storyline. She discerned that both sisters in the story would benefit from embracing each other’s strengths as they confront the danger that looms in their midst. “If they each adopt a trait from the other, they can solve the murder,” she added, suggesting that collaboration and understanding are crucial in overcoming adversity.

When asked about their future adventures, the sisters showed eagerness to embark on another trip together, perhaps devoid of the murder mystery theme. While Morgan deftly joked about Nina’s inclination to chat with strangers—which resonated with her curiosity and desire for connection—Nina acknowledged that this aspect of her personality might lead to unintended plot intrigue. Nevertheless, she appreciated the many lessons their previous journey imparted.

The charm of their sisterly relationship shines through as they both look forward to a possible return to the Grand Canyon or elsewhere in Arizona. Through writing this novel, Nina has developed a newfound appreciation for the desert landscape, further solidifying the bond they share as sisters.

In the closing exchange, Morgan light-heartedly reminded Nina to ensure their future travels remain free of perilous plotlines, to which Nina responded with typical sibling humour, “We’re sisters. Anything’s possible.”

*My Sister Is Going to Kill Me* is now available in bookstores, inviting readers into a world of mystery that draws deeply from the life experiences and relationship dynamics of its authors.
