Christopher Rowe is back and there are more puzzles, riddles, and secrets to uncover in this follow-up to the Indie Next pick The Blackthorn Key, which was called a “spectacular debut” by Kirkus Reviews in a starred review.

The Black Death has returned to London, spreading disease and fear through town. A mysterious prophet predicts the city’s ultimate doom—until an unknown apothecary arrives with a cure that actually works. Christopher’s Blackthorn shop is chosen to prepare the remedy. But when an assassin threatens the apothecary’s life, Christopher and his faithful friend Tom are back to hunting down the truth, risking their lives to untangle the heart of a dark conspiracy.

And as the sickness strikes close to home, the stakes are higher than ever before…

    I knew this would kill me but I went for it anyway. Why oh why do I do this to myself? Well.. it was SO worth it. The Mark of the Plague by Kevin Sands was wonderful. It had everything you need in a book, humor, action, and mystery. It’s about Christopher, an apothecary-in-progress, who is his own master. He is now in the middle of the ‘plague-age.’ He has to, now, use clues and hints left by his old master to figure out the cure for the plague, with a few obstacles on the way. This book was a definite yes for me. And I say this once again, Kevin Sands’ writing is P.E.R.F.E.C.T.I.O.N The entire plot, characters, and setting complement each other SO PERFECTLY. *Characters* Christopher was the absolute best. He is so smart and funny that you got to love him. He is such a caring and clever character that rarely makes it in Middle-grade novels. Tom was one of those ‘side-kick’ characters that aren’t really ‘side-kicks.’ The very fact that Tom is technically a side-kick doesn’t get acknowledged in the novel. Christopher, who is the main character, doesn’t treat Tom like just a person that wants to help. No. He treats Tom like his equal. Like a true friend. And that is beautiful. The friendship in this book is just..beautiful This book, This series, Kevin Sands, Are the ABSOLUTE best! So thank you for making me satisfied with such great writing and therefore killing me. Five stars from me!
