[New York, April 23rd, 2024] – Apicem Publishing is thrilled to announce the release of “Aria & Liam – The Baker Street Mystery,” the latest addition to the adventurous and historical middle-grade book series written by Coline Monsarrat. Launching on April 23rd, 2024, this exciting and fast-paced adventure follows 13-year-old best friends Aria and Liam as they attempt to save the enigmatic author, Sir Arthur Conan Doyle, from a sinister kidnapping plot.

In “Aria & Liam – The Baker Street Mystery,” readers are transported to the streets of 1900s London as Aria and Liam, best friends and junior detectives, embark on their most cryptic case yet.

Joined by the daughter of the renowned author Sir Arthur Conan Doyle, the duo must race against time to rescue Doyle from an enigmatic kidnapping plot. But when Doyle announces Sherlock Holmes’s return, he suddenly vanishes, plunging them into a world of hidden clues and shadowy figures.

Could the mastermind behind it all be a rival author, a member of a secret society, or someone from London’s high society? With each chapter bringing a new surprise, Aria and Liam’s smarts and bravery are put to the ultimate test. Will they prove themselves as clever as the legendary detective, or will they meet the same fate?

“The Baker Street Mystery” is perfect for young readers aged 8 to 12 who love a suspense-filled mystery intertwined with a fast-paced adventure. 

What makes this book truly special is its exploration of how various professions can have a significant impact on our world. Coline Monsarrat, author of “Aria & Liam – The Baker Street Mystery,” explained the motivation behind the book: “As a longtime enthusiast of detective novels, I wanted to delve deeper into the genre with this book, particularly to spotlight how one author revolutionized an entire industry through his creation of the iconic character, Sherlock Holmes. My intention in crafting this narrative was to highlight the profound influence that individuals in various professions can wield upon our world.

Additionally, after seven books in the series, Monsarrat decided it was time to reveal Aria’s dyslexia, a characteristic subtly hinted at throughout earlier installments through her spirited demeanor. Monsarrat stated, “Why? Because I wanted to highlight that living with dyslexia should not hinder one’s potential to become an author. I, too, live with dyslexia, and for the longest time, I believed it barred me from pursuing writing due to my frequent grammatical errors or unconventional expressions. However, being an author transcends mere grammar; it’s about telling stories to the world. I aspire for every child to grow up embracing the belief that no obstacle should deter them from realizing their dreams.

Throughout the series, Aria and Liam’s unbreakable friendship and sharp wits have been central to their adventures. From ancient Egypt to Rome, Atlantis, the Inca Empire, and even Dracula’s realm, the duo has outwitted adversaries while unraveling historical mysteries. With each page brimming with history, humor, and heart-pounding action, “Aria & Liam – The Baker Street Mystery” continues to captivate young readers with its surprising twists and turns.
