Jonathan Stroud cannot write a sequel soon enough. Lockwood & Co. is my new favorite series. Stroud has taken a little bit of Sherlock Holmes and a lot of John Bellairs and thrown them together to create a captivating, horrific, and witty mystery. Stroud's dry wit, (which is sometimes of the blink-and-you'll-miss-it kind) is not overused. The characters, thrust into a truly fantastic world where ghosts are real and only children can save us, are completely believable.
Lockwood, Lucy and George are truly a team, though even Lucy admits that they don't include George enough in the actual action. All three have their flaws, but are saved by the strengths of the other team members. In The Whispering Skull, we learn a huge cliff-hanging secret about Lockwood. We see what George is truly capable of when pushed. And we see how important loyalty and family are to Lucy.
Though maybe not as scary as the first book, The Whispering Skull, gives the reader a lot of shivering, hold your breath, moments, where once again the scariest, most dangerous things in the world are the actual people and not the ghosts.
A must read.
