Oh my dear R.L., how you've wasted your talent. The Babysitter series had potential for greatness, but it mainly peaked in the second book, offering more absurdity in the final books of the series. R.L. pulled the rip cord on any attempts at a grounded plot and goes full on supernatural. Sigh. Why R.L.... why?
Jenny Jeffers is back from her year in the mental hospital. Recovered from the trauma of now dead Mr. Hagen's attempt to murder her (but surprisingly no leftover trauma from the attempted murder by a very much still alive dingbat secretary), Jenny is just trying to acclimate to life on the outside. Her friends Rick and Claire are back, along with her boyfriend Cal, and her mom, who finally seems on the upswing with a new job and man in her life.
Jenny Jeffers lives in a new home, and spends her days trying to relax and live a normal teenage life until she is approached by Mrs. Warsaw, a widower of twin boys and a girl. Mrs. Warsaw obtrusively asks complete stranger Jenny to watch her kids for 15 minutes, because hey, this is the 80s and trust in humanity is still kind of a thing.
Jenny likes the kids and finds enjoyment in babysitting Sean, Seth, and Meredith, although if you want my opinion that you didn't ask for, I would have tapped out from the fighting little monsters after one visit. But no, our Jenny is a natural.
Despite enjoying the kids, Jenny has a weird experience at the house of feeling supernatural coldness in the room. As she does in earlier books, she tries to talk herself down, but ultimately decides she's uncomfortable at the house. It's the first mental soundness we hear from Jenny, but will it last? No, of course not. Because in order for the plot to work, Jenny has to have resounding devotion to three unknown kids she's known all but 15 minutes and an allegiance to oddball Mrs. Warsaw over her own comfort.
This is how she winds up committing to the watch the kids again. And again. And with each visit, comes an escalation of oddities. More supernatural cold feelings. Creaking and footsteps in the attic, seeing a girl's face in the attic, and nightly runs of a little boy and howling animal in the middle of the night in her yard. Weird. And things... just get weirder. Because now, Jenny is hearing voices warning her of impending death, and finding herself near victim to a cake knife turning on her and a garbage disposal that wants to eat her arm. (At least no phone calls this time) Despite all this, and in the realm of dumb fiction, Jenny bottles this all up, only telling Claire (who betrays her trust and tells Ms. Jeffers) and stubbornly continuing to babysit, because she has a grotesque need to figure out what's going on and prove her sanity to ... herself?
And so, she babysits one final time (to the opposition of Ms. Jeffers) only to find the truth- sweet and kind twin Seth is actually a ghost that has been trying to kill Jenny. Yes, I know, you have a lot of questions, such as, how did Mrs. Warsaw and Jenny go the whole book without dialogue about twin Seth, or how does a ghost boy consume cake? Rest assured, my friends, none of your questions will be answered. So Jenny, loses her marbles, and throws a glass vase at a bathroom mirror in an attempt to destroy the reflection of Seth, cutting her self in the process, just as Mrs. Warsaw conveniently comes home. And of course, everyone is now on the "Jenny is crazy train," with Ms. Jeffers being especially concerned.
The book isn't done yet though. You see, proving her sanity (or insanity in my opinion) is really crucial here, which is why, when she sees the girl in the attic saying "Help Me," she decides to once and for all figure it out...and so, she sneaks into the house while Mrs. Warsaw and the kids are out, and lets the girl ghost out of attic, despite protests from Seth the ghost. We find out, despite contradictory accusations, that Seth was a boy who attempted to kill his babysitter, only to die himself in the process. And somehow this final culmination of ghost fighting leads to the final death of both ghosts. Cal and Ms. Jeffers come over just in time to miss all of this, but to find Jenny feeling mentally stable now that she has seen out the end of the horrors she's faced. (Cue the light-hearted ending joke about babysitting- palm slap)
Here's the real plot hole issue I have here, besides my disdain for the whole plot in general. We're given the impression, throughout the story, that the attic needs to stay locked. This is explained that Sean and Meredith knew what was going on with Seth and had an allegiance (through fear) to him. But are we to believe Mrs. Warsaw never opened the door to the attic? And why would Mrs. Warsaw be exempt from the supernatural occurrences of the house? If the kids aren't exempt, why would Mrs. Warsaw be? This is just one of many questions I have about this book.
Don't ask why, but I believed these books were building up for the return of Mr. Hagen. Heck, I could have even stood by a Mr. Hagen ghost revenge plot.
But no, sit back, relax and enjoy the menagerie of nonsense as the Babysitter series ends with an off the rails plot.
