Unicorne Files Books in Order

Unicorne Files is Chris d'Lacey doing paranormal mystery instead of straight dragon fantasy, and the result is a noticeably darker series. The lead is Michael Malone, a boy whose father vanished on a secret mission years earlier. Michael is still carrying that loss when he discovers that he has a frightening gift of his own, the power to alter reality.

That discovery pulls him into UNICORNE, a hidden organisation that investigates the weird, the dangerous, and the things ordinary people are not supposed to know about. If the dragon books often begin with a house or a family, these books begin with a case. Michael is sent into strange situations that look small at first and then open into something much bigger, and much nastier, underneath.

The cases are part of the fun. A rescued dog on a cliff edge. A sickly classmate. A dead girl whose story will not stay buried. A comic shop with something badly wrong at its centre. Later, there are ghosts, a shape-shifting crow, telekinetic forces, dragon-linked secrets, and shifts in reality that keep both Michael and the reader slightly off balance.

These books are spooky on purpose.

What ties everything together is Michael himself. He is not just solving mysteries for the thrill of it. Every step into the UNICORNE world might bring him closer to the truth about his father, Thomas. That makes the series more emotional than it first appears. Michael wants answers, but the more he learns, the less sure he can be about who deserves his trust. Even fellow agents can feel unreliable.

The tone sits somewhere between adventure, science fantasy, and ghost story. It moves quickly, but it likes to leave a chill behind. D'Lacey keeps the prose accessible, yet he does not sand off the unease. For younger readers, this is one of his edgier worlds. For older middle grade readers, that edge is exactly the appeal.

Read the trilogy in order, starting with A Dark Inheritance. The cases connect, the mythology deepens, and Michael's personal story carries straight through to A Crown of Dragons. If you want d'Lacey at his creepiest and most conspiracy-minded, this is the place to start.
