So this middle book in the three-part "Beyond the Spiderwick Chronicles" series ostensibly tries really hard to improve on the first one, and to broaden and expand the scope of the characters and plot, but in the end it just falls flat. Story-wise, basically there are giants wreaking havoc all over Florida, and it's up to a group of step-siblings (plus or minus a girlfriend or a trio of recalls from other series) to figure out how to get rid of them.
The authors thankfully managed to keep themselves out of the book this time, but at the last second couldn't resist blurring the lines between this series and the original Spiderwick series as the Grace kids make another appearance, which just comes across as unnecessary throwback. It seems like they're really trying to develop these characters, but it's just not working for several reason(s): They are inconsistent; their progression is unnatural and abrupt; they all still feel really bland and shallow; Nick is still just really unpleasant! In fact, all of the kids are deceptive and disrespectful to their (obviously) clueless and negligent parents. Some characters make appearances for no apparent reason--Noseeum Jack had a lot of potential, but disappeared just as suddenly as he appeared at the end of the previous book. The parents in the picture are utterly ineffective, presumably because they have to be in order for the kids to run around fighting giants and whatever, but there has to be a better way to write these relationships. The writing is probably even weaker than in The Nixie's Song (speaking of, the nixies are pretty much absent throughout). The poor kids seem just as flat in character as the singular-minded giants. There were some arbitrarily-inserted new creatures, but even when they're supposed to be threatening and tricky, they more often than not they don't follow through with their eerie warnings, or they disappear entirely. The mysteries and clues presented throughout aren't very well-developed or -placed, or even referred to very often, which makes their reappearance as the missing piece of the puzzle seem random and confusing (I had to go back and re-read parts to even remember if certain elements were even mentioned earlier). And then the whole plan to actually defeat the giants seems so bewilderingly simplistic it's kind of insulting. The deal with the mermaids doesn't even make sense, but could have been a really awesome plot element, especially regarding Julian. It's like a five-year-old concocted out a plan (which is sort of the idea, but it has to at least make sense and be a little believable), and the teenagers involved just went right along with it. And then, just like the nixies and their disappearing/reappearing act, the last page indicates that basically the entire conflict and plot of this book was filler, totally unnecessary. They spent the entire book figuring out how to get rid of the giants, and going through with this murky and implausible plan, only to discover they have to bring them back.
The attempts to address heavy themes are still here, though sort of in the background, but the language is a little more age-appropriate. Unfortunately, not even the design seemed as polished or impressive this time around. I'm starting to lose interest in this DiTerlizzi a little bit. It's just not as attractive as the first time around for some reason. This world has potential, but it's being squandered by opportunistic spin-offs. Why should kids' books be poorly-written and weakly-structured?
Also, that's one sturdy microcassette player to be completely submerged in seawater, then resurface in perfect working order...
