I loved the witty humor, how well the story flowed from one character to another, the world of time traveling (and other sciences!) and how much fun I had with this book! I couldn’t put it down. Thank you Simon Kids for our gifted copy!

3.5 stars.

Young Bertie Wells has always had the imagination of an inventor. But when he accidentally creates a black hole in his bedroom, he's not prepared for either that or for the sudden appearance of a strange woman bearing an invitation for him to attend the Everwhen School of Time Travel and Other Odd Sciences. Not only is this a school set outside of the time-space continuum for bright students such as himself, it's also offering him a highly coveted Time Scholarship, by way of the kind, if eccentric, Professor Darla Marconi.

Bertie doesn't want to tell Professor Marconi that the black hole was created less on purpose than by accident. The last thing he needs is further ammunition for his disapproving father's continuing belief that Bertie is never going to amount to anything. This, perhaps, might be his best chance of escaping the drudgery of finding a trade to apprentice in, so off he goes to Everwhen, little realizing that he's embarking on the adventure of several lifetimes.

Everwhen is weird and wonderful, filled with fantastic scientific marvels from all eras of time. Bertie quickly makes friends with Millie da Vinci, the much put-upon younger sister of the celebrated Leonardo, and Zoe Fuentes, a brainiac recruit from 2025 who's accompanied everywhere by her trio of colorful slimes. The three new friends are assigned, as all first-year Time Scholars are, to Haz-Labs, the clean-up crew of the entire school. Haz-Labs is not only considered their extracurricular for the whole of first year but also makes up their team for the Ever-Ring Competition, a school-wide contest that rewards the best half-year student invention. This is a big deal because the winning student's lab gets the best school perks, including choice of classes, housing and extra free periods.

Hyper-competitive Zoe wants to make her mark on the school by being the very best, while Millie's insatiable curiosity and poor impulse control have her bouncing from one madcap project to the next. Bertie, on the other hand, couldn't feel like more of a fraud. While he certainly has the ideas of an inventor, he doesn't have anywhere near the scientific chops that the others do, and soon finds himself bottom of the class.

That soon becomes the least of his worries tho, when an invention that he and Millie dreamt up is found at the last-known whereabouts of a disappearing dean. With Zoe withdrawing further into herself and time emergencies on the rise, will Bertie be able to get to the bottom of the mysteries plaguing Everwhen? The fate of all existence could very well hang in the balance!

Time-travel is a great twist on the ever-popular boarding school subgenre, and The Doomsday Vault is a great start to this series. The tale itself is bouncy and fun -- but leave any expectations of rigorous adherence to historical accuracy at the door. Older speculative fiction aficionados will, ofc, immediately recognize Bertie for the historical figure he's based on. Almost everything about Bertie's life in this book is only loosely based on his real biography, but the emotions are detailed both believably and movingly. I especially loved the rapprochement between Bertie and his dad. I also genuinely appreciated the heart-to-heart talk he had with Dean Chen near the end about his own enrollment in the school, even as I kept wanting to reassure him that someone is always at the bottom of every class: that's just how rankings work! As long as he's done his best, that's something to take pride in.

Thank you to Netgalleyand the publisher for providing me with an advanced copy of this book. The cover was very eye-catching and I am sure that will draw kids in. However, the book was very confusing with the jumps in time, the unexplained scientific elements like Schrödinger’s cat, and other fantastical elements. I just don't think the kids will gets it. The message gets lost somewhere in the time stream.

*Thank you to Simon and Schuster Children's Publishing for letting me read an ARC of this book through NetGalley!*

Overall Thoughts:
I will preface this by saying that I'm not a big fan of time travel books in general, but I found this book to be a little confusing to follow at times and overall lacking in logic. If you read this just for the vibes, the book is decent, but if you look too close at the logic it all starts to fall apart. Overall the characters and atmosphere were pretty good and I think those aspects kept me the most intrigued. Unfortunately, I found there to be a plethora of typos (though that might have been fixed in the final copy idk) and the story was reasonably predictable (there were definitely some moments where I think I was supposed to be surprised and I wasn't). There's something here that's pretty enjoyable and unique, but it gets a bit overshadowed by the rushed pace of the story.

Time travel is the best! Bertie attends Everwhen School but wasn't prepared for it. How did he get there? Well, that's the mystery aspect of the book. The plot was both funny and educational with historic events. Great adventure and start to the series.

This was such a fun adventure that I was looking for and enjoyed the children’s fiction element to it. It had what I was looking for from Thomas Wheeler and had a charm to it. It uses the inter-dimensional school element perfectly and enjoyed the time-travel. The characters worked overall and was glad I got to read this. I hope there is more in this world as I really enjoyed this.
