What's the Story?
It's the spring of 1665, and Charles II is on the throne, though none too securely. Closer to home for 14-year-old apprentice Christopher Rowe is the fact that "in the past four months, five men had been butchered in their homes. Each of them had been tied up, tortured, then slit open at the stomach and left to bleed to death." Then his beloved master, apothecary Benedict Blackthorn, becomes the latest victim, leaving Christopher a note in code inscribed "nemini dixeris" ("tell no one" in Latin). Soon Christopher and his best friend Tom are trying to decipher THE BLACKTHORN KEY, solve the murders, and stay alive as they unearth a plot that threatens not only the king but the entire world.
Is It Any Good?
First-time author Kevin Sands delivers irresistible characters, cool knowledge, intrigue, and lots of explosions as a 17th-century apprentice tries to solve his master's murder. Over the course of this exciting page-turner, readers will learn quite a bit about day-to-day life in 17th-century London, secret messages in code and Latin, and chemistry. Purists might quibble about the occasional anachronism, such as referring to characters "aging out" of an orphanage, but it's for a good cause: making a lot of potentially forbidding knowledge not only accessible but also spellbinding.
Parents be warned: There are definite "kids, don't try this at home" moments. It's nothing they can't find on the Web any day, but The Blackthorn Key includes detailed recipes for explosives, particularly gunpowder and something like nitroglycerin. Some of the compounds are described with archaic names such as "aqua fortis" (nitric acid).
