This book was adorable! It felt familiar. Kind of like a Dan Gutman, Mr. Lemoncello, Westing Game mash up by what a fun story! Jake and his mom move to an apartment owned by his relatives but find that the building has more to offer than he thinks when he stumbles back in time to look for help to save the building from being demolished. Great narration by the author, which can go either way. Finished this today at work!
