How to Read Aimee Hix’s Novels
If you are planning to dive into the mystery novels of Aimee Hix, the best path forward is straightforward. Hix has focused her novel-length career on a single, compelling protagonist: former police officer turned apprentice private investigator Willa Pennington. To fully appreciate Willa's character arc, the development of her relationships, and the recurring shadows of her past, you should read these books in their exact order of publication.
Willa Pennington, P.I. Series in Publication Order
Since the series currently consists of two novels, following the publication order is identical to following the chronological order of the story. Here is how they line up:
- What Doesn't Kill You (2018) – Willa's debut case. She agrees to help a neighbor's granddaughter escape an abusive relationship, only to find herself investigating a murder.
- Dark Streets, Cold Suburbs (2019) – The follow-up. Recovering from the events of the first book, Willa takes on a cold case for a former mentor while helping a teenager being stalked by an ex-boyfriend.
Exploring the Willa Pennington Universe
Hix’s mystery novels stand out for their atmospheric and grounded portrayal of suburban Virginia. Unlike standard Washington D.C. political thrillers, Hix moves the spotlight to the nearby suburbs where strip malls, cul-de-sacs, and quiet neighborhoods hide deep-seated secrets.
1. What Doesn't Kill You (2018)
Willa Pennington is a former cop who left the force to escape the traumatic duty of delivering death notifications and the weight of wearing a bulletproof vest. She is trying to rebuild her life as an apprentice investigator at her father’s private detective agency in Fairfax County, Virginia. When her neighbors ask her to help their granddaughter, Violet, leave an abusive partner, Willa agrees to step in. However, when she arrives, she finds the boyfriend dead and Violet missing. With her father out of town, Willa must take charge, confronting a web of lies and her own personal grief to clear Violet's name.
2. Dark Streets, Cold Suburbs (2019)
In the second book, Willa is dealing with the physical and mental fallout of her first case. In an effort to reclaim normalcy, she starts taking self-defense classes, where she meets a young woman named Aja who is being stalked. Simultaneously, her former police mentor, Detective Jan Boyd, asks her to look into a decades-old cold case. When a key suspect in the cold case turns up dead, Willa's personal and professional cases collide, demonstrating that danger is just as prevalent in the quiet suburbs as on the city streets.
Charity Anthologies and Short Stories
In addition to her main novels, Aimee Hix has contributed short stories to notable mystery anthologies. These stories are excellent companions for readers who want to explore more of her writing style or see Willa in a shorter format:
- Killing Malmon (2017) – A collection of short mysteries edited by Kate and Dan Malmon. Aimee Hix contributed a short story to this anthology.
- Revenge of the Widow Malmon (2020) – A follow-up charity anthology where Hix contributed a short story that explicitly features her signature character, Willa Pennington.
What to Know Before You Start
Aimee Hix brings a unique background to her writing. Before she became a full-time mystery novelist, she spent two decades working as a federal defense contractor in Northern Virginia. This background gave her an insider's view of bureaucracy, human conflict, and the complex structures of security and justice, which translates directly into the procedural realism of her novels. Her writing style blends elements of gritty classic private eye noir with the warmth and emotional depth of modern suburban mysteries, earning her comparisons to genre giants like Sue Grafton and Sara Paretsky. The books feature a strong focus on secondary characters, including Willa's father and her boyfriend Seth, an ATF agent, meaning that reading them out of order will spoil significant relationship dynamics.
