Detective of the Crown and Missing Gemjewel

Eleven-year-old Alfie O'Love has been raised on bedtime stories about the wondrous Erinmerald Kingdom-until St Patrick's Day reveals the stories were true. When Alfie's eyes begin flashing emerald green, he discovers he belongs to a hidden world divided into Four Realms: Lovely Spring, Blissful Summer, Harmonious Autumn, and Peaceful Winter, all kept in balance by the Songbird Gemjewel. But when Gemjewel vanishes, the seasons begin to collapse into chaos. After the legendary King Raghnall summons his Grandad James, Alfie joins a secret mission across the realms to solve the mystery before the balance breaks completely. Alongside his fiercely brave friend Clíodhna, her mischievous brother Finnegan, and his warm, loving family, Alfie must outwit the spirit villain Mayhem Murdock, who wants to force a terrifying fifth season into existence-one that will finally give him the "bride" he believes destiny owes him. To stop him, Alfie must rely not on strength, but on his sharp instincts, kindness, and a strange gift called a deviation-a power that lets him notice what others miss. As the stakes rise, Alfie must prove he is more than a child in a grown-up mystery. He must become what Erinmerald needs most: a detective brave enough to protect wonder itself.
