Lockwood. A set of two books with a half cover by Polina Dr. Graf

"The Screaming Staircase"
The first book in the series by the famous Jonathan Stroud is an excellent fantasy for true connoisseurs of the genre! "Stroud is a genius" - this is how Rick Riordan succinctly described the British writer Jonathan Stroud.... And indeed, it is impossible to tear oneself away from J. Stroud's books! This series has become just as popular and has entered bestseller lists worldwide, just like the "Bartimaeus Trilogy." The agency "Lockwood & Co," run by three teenagers, is engaged in the battle against ghosts that have invaded London. As always, Stroud masterfully creates an unparalleled alternate world where his contradictory yet so attractive characters operate. A true literary fusion - the plot is a mix of detective investigations, a tense search for answers, mysticism, all set in the atmosphere of an almost steampunk London.
"The Whispering Skull"
My name is Lucy Carlyle, and I work at the agency "Lockwood & Co." There are just three of us: me, Anthony (also known as Lockwood), and George. We catch ghosts and save London from them. It sounds simple, but in reality, it is much more complicated. There are so many ghosts and their varieties, and most of them are deadly dangerous, and even our super weapons: rapiers, iron chains, and jars of Greek fire - are not always effective. However, there are no cowards in our agency.
It seems that our assignments are getting more difficult each time. In one of the graves we had to open, we discovered an ancient bone mirror with monstrous power. Anyone who has ever looked into it died in horrible agony. It's rumored that it was created by a mad necromancer from real human bones. Brrr! It's better not to think about it. Now, Lockwood, George, and I have to not only solve this deadly mystery but also resist the temptation to look into the terrifying mirror, which seems to possess its own will... In short, another case for crazy agents!
