"With the help of some unexpected, and rather ghostly, allies, Lockwood & Co. must battle their greatest enemy yet, as they move ever closer to the moment when the earth-shattering secret of 'the problem' will finally be revealed"--
I'll write a proper review soon (am travelling and short on time). Suffice it to say for now that this was a brilliant ending to the series. Everything was neatly wrapped up and it left enough there for any future Lockwood & Co stories without making me feel unsatisfied.
The Empty Grave didn't show up in the Goodreads readers choice for 2017, so I did a write in vote for it in the Middle-Grade category. It definitely belongs there.
