Addison's mother wants to sell their comfortable old house and move into a townhouse in a new development across town - a shoe box near a shoe factory, Addison calls it. As usual, Addison's brain goes into overdrive as he tries to solve two problems: first he must get his mother to see their old house in a new light, and then he must figure out who is responsible for a rash of neighborhood break-ins that make his mother feel unsafe. With the help of his friend Sam, he puts his own unique spin on optical illusions (and home decor) and ends up surprising everyone, even himself.
Addison Addley hates math. He hates public speaking too. Actually, he hates anything that involves work, but he only has a couple of weeks to write and memorize his grade five speech. The problem is, he can't think of a single topic. When he finally comes up with an excellent idea for a speech, it almost writes itself, but it's his poor math skills that make speech day unforgettable.
When master fact-gatherers TJ and Seymour are asked to join the school Quiz Kids team, TJ thinks Seymour should take the stage at the upcoming contest against the high-pressure Fairview School team. TJ is already more than occupied rescuing his cats and helping Gran get ready for her upcoming trip to Belize. When he goes with his dad to help with a renovation job on a huge house on Fairview Hill, he and T-Rex tangle with a rich girl and her giant dog, Frooie. Then Seymour develops stage fright, Alaska goes missing, and the girl from the big house shows up on the Fairview quiz team. TJ knows he has to sort things out - fast!
TJ may not like cats, but that doesn't stop a taxi from showing up at his door bearing his grandmother's four felines. Killer, Cleo, Kink and Maximillian the Emperor, Max for short, invade TJ's life and replace dinosaurs as the topic for his school project. His friend and partner for the project, Seymour, is deeply disappointed; the cats in his drawings all come out looking prehistoric. The animals' presence in TJ's house leads to a series of adventures, one involving the police and another involving a mass escape.
In this sequel to TJ and the Cats, TJ and his best friend Seymour are back, joined by a classmate Amanda. TJ does not believe in ghosts. So when he agrees to create a haunted house in his own home as a fundraiser, he does not anticipate problems, at least not until it turns out that a ghost may inhabit the spare room in his century-old house. The ghost, real or imagined, leads TJ to some fascinating family history. TJ finds a way to bring that history alive for his family. The kittens, offspring of two of the cats from the first book, lead the way.
Jeremy longs for a pet, but he doesn't know what kind of pet to get. When his parents agree that he can start a pet-sitting business in order to try out a variety of species, Jeremy has no idea what adventures are in store for him. Pet after pet is eliminated from his "To Get" list. In the end, not a single animal seems suited - until a favorite relative comes up with a surprising solution.
TJ overcame his fear of cats in TJ and the Cats and his fear of ghosts in TJ and the Haunted House. Now, he's not so keen on facing his fear of failure. His best friend Seymour is determined to come up with the latest greatest invention and TJ's gran expects TJ to build a rocket. The kittens, T-Rex and Alaska, are eager to get involved. When the first rocket that TJ builds plummets out of the sky, no parachute in sight, TJ is sure that his efforts are doomed. But are they?
