i dont normally pick up books randomly, but this was showcased at my local library and i have been in a mood for mystery books this past week - so i thought ‘why not?’

for this book to be described as ‘a novel in clues,’ i was expecting more of a ‘whodunnit’ like premise, but it felt more like general contemporary fiction to me. the writing style and storytelling reminded me a lot of jonathan tropper and cynthia d’aprix sweeney. i wish there had been more of a mystery element to this, but the fa

This book begins with an intriguing opening line, "On the morning he was to die, the old man woke early and set about making breakfast". The book did not fail to deliver and I found myself not wanting to put it down but yet wanting to make it last as long as possible. A famous mathematician, Isaac Severy, is found dead, but leaves a cryptic note to his granddaughter Hazel with instructions regarding the last equation he was working on. This equation is of interest to several people as it proves ...more

When I first started reading this, it seemed as if was going to be a treasure hunt of a novel. The treasure belonging to a highly touted mathametician, and the treasure a brilliant equation, which many seek. When Isaac died under suspicious circumstances his granddaughter is left a letter containing clues as to where this equation is, and also to whom he wants it given.

But....this is not exactly a treasure hunt, it is also or maybe more about a family with the majority of family members having a

Gotta love Goodreads for letting me rate my own book. It’s been such a thrilling launch. Much appreciation to all the Book of the Month Club members who chose Isaac Severy (and are posting such gorgeous pictures!), and to all the readers out there who took a chance on the Severy family. Thank you!

This book totally surprised me. I was expecting a fun, lighthearted adventure/mystery story—which it definitely was—but also got a novel about death and the universe and family. The main characters (because the story focuses on more than just Hazel like the blurb leads you to believe) are flawed and complex and relatable. I particularly liked Philip's storyline, though I loved Hazel and Gregory too. And the mystery aspect of this novel definitely had me turning pages and guessing at what would h ...more

The Last Equation of Isaac Severy is a delightfully fresh literary mystery. It was just the thing to get me out of a the little slump I'd been in. I wasn't in the mood for something terribly heavy or terribly morbid. I'm always up for quirky characters. No matter that the quirkiest character was deceased prior to Chapter One. (Of an apparent suicide. In a hot tub. With a string of Christmas lights.)

Why I Love It
By BOTM Guest Judge Sophia Bush

Everything in nature follows mathematical patterns: Planets follow elliptical orbits, flowers follow the Fibonacci sequence, and snowflakes crystallize with complex symmetrical elegance. Clues to the intricacy of the universe, if you will, and there’s nothing I like better than a finely-crafted succession of clues. Which brings me to this engaging, clever book.

Never fear, this is no tale of dry mathematical theory. It’s a sharp puzzle mystery, full of

Imaginative premise and superb writing could not save this story from being overwhelmed by its themes. Predictive mathematical models, chaos theory, dysfunctional family dynamics, child abuse, vigilante justice and a pseudo-incestuous relationship just to name a few. Throw in a multitude of characters and an exploration of fate and you have a muddled tale I could not decipher. This is another book that I kept reading for its ambition and I thought it would all make sense in the end. Instead I wa ...more

The Last Equation of Isaac Severy is an entertaining read. I majored in math in college and loved that aspect of the book. Hazel is a likeable if somewhat naïve protagonist, and her hunt for her grandfather’s secret last equation kept me reading. I waited a few days to write my review because I was not sure how I felt about the ending; two aspects troubled me a bit: the location of the equation and the identity of the vigilante. Sadly, waiting a few days didn’t help me resolve my thou

Hazel Severy has been set on a quest by her recently deceased grandfather, Isaac Severy, a renown mathematician. His letter to her stresses secrecy and suspicion of everyone else within the family and without. This charming narrative poses puzzles and clues to help her solve find his last equation and deliver it safely to his only trusted friend. Even without a facility for numbers, I found the puzzles interesting and the book enjoyable.

This was a huge letdown. It was messy and anti-climactic. I didn't enjoy it very much at all.

Intelligence fades. Sex fades. The thrill fades. Where is the wisdom that is supposed to compensate for the loss? But if his father's death had taught him anything, it was that there was no real wisdom with age, only forced compliance.

This book was my first great read of 2019.

Isaac Severy was the paterfamilias of a family made up of exceptional scientific and mathematical minds and academic disappointments, in some cases both at once. When he is found dead of an apparent suicide at his home in

This book was not at all what I was expecting. I thought there would be a mystery but instead it was primarily about Isaac's large dysfunctional family. It wasn't what I was looking for. I received a free copy of this book from the publisher.

To call this book the "adult Westing game" is a farce, and is truly a disservice to both books.

The Westing Game was probably my favorite, most-read book as a child. I believe it just appeared one day in my little library and I read it back to front a million times. It was great because it had a mystery and the clues were included in the book-- you could unravel the mystery through deduction or by solving anagrams or puzzles.

This book pretends to have a mystery as the central point of the s

I am the polar opposite of a mathematical person, but when I read the premise of this book, I was sucked in and knew I had to read it! Mystery, family drama and secrets, clues for the character (and for us as readers), wittiness with a side of bookstore owner?! Yes please! I enjoyed this book, was sucked into the world and was rapidly flipping pages to find out the ending. And Book of the Month?! Yay!

This is an entertaining story by a new novelist, Nova Jacobs. It is the tale of a dysfunctional family and their relationships with one another. It is also a mystery. The patriarch of the family dies, and leaves behind a note to his daughter Hazel, giving her a difficult task of finding his last equation and delivering it to the right person. Others are also looking for the equation, because it is proven to be able to accurately and precisely predict the future.

The family is filled with geniuses

I received an ARC of this novel from Touchstone Books via my position as a bookseller for Barnes & Noble. I picked it up mostly because the back blurb name drops Mr. Penumbra's 24-Hour Bookstore which I absolutely adore. Let me say up front that that comparison is wonderfully apt. If you love that or Robin Sloan's other novel, you'll fall right in love with the Severy family.

I am a self-proclaimed math nerd and I do love the subject, though I feel a bit inadequately compared to the characters in this novel. For these reasons, it made me love this book even more. However, taking that out of the equation (ha, see what I did there), I thoroughly enjoyed this murder mystery, the way this family all tied together, and I couldn't wait to see how everything would turn out. This book kept me intrigued from the very beginning and though I couldn't wait to finish it, I'm now ...more

This one took a long time to hook me - not sure if that was due to my sporadic reading this month or the story itself. I almost moved on 1/2 way through but decided to give it one more try over a weekend getaway and I was glad I did overall (but also happy to move on to the next story).

This novel ended up being rather different from what I expected. Instead of a somewhat wild and exuberant romp, it was instead a measured and character driven tale more reminiscent of Allegra Goodman than Thomas Pynchon or Jess Kidd. There is quite of bit of family dynamic involved, easily as much as mathematics and academia. It was certainly more refined and emotionally compelling than I had expected. I found it to be a very strongly and confidently written novel, especially for a debut.

**I received a complimentary copy of this book from the publisher in exchange for an honest review. I received no additional compensation**

I'll be recommending this to everyone who says they are in a reading slump. The story is fresh, original, and gripping. While it is being touted as a mix between The Family Fang (I didn't read) and The Storied Life of A.J. Fikry (which I loved), I would like to add in Where'd You Go Bernadette

Just right for my mood, a nice cerebral mystery. Apparently it’s difficult to impossible nowadays to describe a new novel without referencing another, however tangentially connected, but really this one is very much its own book. Seriously, yes the protagonist owns a bookstore, but it’s a relatively inconsequential detail in the grand scheme of things. It also doesn’t need to describe itself as a novel of clues, a lot (most?all?) of mysteries have clues. Going by the description I even thought m ...more

This is one of the few books I would consider reading again (I just really don't do that very often...I find subsequent experiences are usually less powerful, so why bother?) just because I'm left feeling like I maybe missed a few things here and there? Or maybe I just want to see how the mystery unravels, knowing the end now. I found it a little hard to concentrate on the book when I was reading it, but it is nevertheless a very impressive, well-written and elaborately-plotted debut.

“Please, this isn't a Poe mystery; it hardly requires a C. Auguste Dupin level of detection. It took me a few seconds. Most people go around thinking that life is magical and mysterious, filled with all kinds of unknowns. Bullshit. Once you decide the universe is knowable, all kinds of answers become available to you.” 0 likes
