Because I got this ARC on my Kindle, it was very (extremely!) difficult to read: odd artifacts in the text, some text grey while other bits were black, the drawings/artwork didn't render well, etc.. Still, based on the writing alone, I can say that this is in the vein of Lemony Snickett or Trenton Lee Stewart, with the snarky Narrator telling a tale of adventure and intelligent kids outsmarting the adults and will probably appeal to those middle grade readers who haven't gotten tired of that genre.
The Templeton Twins live with their professor father, an inventor. Their mother has recently died and the family is reeling. Their first idea is to convince their father that they should have a dog (they do convince him); shortly after, thanks to walking the dog and getting outside the house, their father moves the family to a new university (Tick Tock Tech). There, he's accused of stealing an idea for a personal helicopter and the accuser, a former student, insists that he get not only credit, but all the royalties, etc. for this. There's a kidnapping, a gunshot, a daring escape...
In addition to the snark factor, there's help figuring out cryptic crosswords and some very unfortunate acronyms. The illustrations will probably enhance this but I couldn't really tell based on what I saw.
