it's fine.

is laurie halse anderson the jodi picoult of the YA set? is this a fair assessment?? jodi picoult's schtick is to just take whatever makes the headlines and structure a book around it. anderson's seems to be to take a teen problem and structure a book around it. (this is excluding her historical stuff, which i liked a lot more than any of the three contemporary problem novels i have read) and it's probably a great thing that she does this - there are so many different problems,

Not anywhere nearly as good as Speak. Kate, the science brain who is nevertheless too stupid (or too driven) to apply to any other college than MIT, doesn't get in (that's not a spoiler, it's the first twenty pages) and her life is turned upside down when her reverend father takes in Teri Litch, an outcast girl, and Teri's mother and young brother. Teri is the catalyst of the hackneyed title, altho we never see anything from her point of view and never get to know her as a character. We don't ge ...more

This book is a work of terrible genius, but I can't go into too much detail because it will break me. Suffice it to say that it's brilliant and that it completely blindsided me and wrecked me emotionally in a way that no other book I've read has ever done.

Catalyst by Laurie Halse Anderson is a sequel/companion to Speak. It's set one year after the events of Speak. This novel is narrated by Kate Malone: straight-A senior, science and math whiz, and daughter of the local reverend. Kate's also a great runner, which is good because Kate's been running from a lot of things:

Kate has been the family caretaker since her mother died. She hasn't been sleeping as she waits to hear from her dream college (she runs instead). And now Teri Litch, Kate's nemesis

Me before reading Catalyst:

Ooh it's written by Laurie Halse Anderson! This should be good!

Me after reading:

Why the hell did I even waste money on this book and WHY did I actually waste precious reading time to suffer through this garbage??

Yep. It was that bad.

And the thing is, I kept reading, mistakenly thinking that this would be one of those books that resolves everything in the last few pages and everything clicks by the end of the novel.

But, disappointingly, nothing was resolved. At all.

{Catalyst* is missing a huge part of what could have made up a good book for me. The main character, Kate, is an ambitious over-achiever science geek with plans of getting into MIT, but her hopes are dashed when she is rejected from her dream school - and it happens to be the only college she applied to. Meanwhile the rest of her life is going crazy as her neighbor's house burns down and the messed up family - including a really rough and tumble girl Kate doesn't get along with very well - move ...more

Last night I dreamed that I was sitting in a gathering of people, waiting for my turn to get up and play my violin. There was a tall guy with dark hair speaking to the crowd, and a little fat blond girl sitting across the aisle from me who the tall guy called an idiot. This struck me wrong, so I told him to stop. Not just because he’d called the girl an idiot, but because he’d yelled it, said it in a mean and condescending way. Instead of listening, though, he slapped the girl on the head.

you know what sucks? when you're about 150 pages into a novel and you get that funky deja-vu-y sort of vibe about it. or, more specifically, when you've had that deja-vu vibe for 150 pages or so and then you realize you've read it before.

yeah, that old chestnut.

you know what's worse? when you remember actively making the decision to stop reading a book, but then, upon accidentally rereading it, realize you've gone past the point of no return and now you have no choice but to see how this badboy

I want to like Laurie Halse Anderson's work, but I don't think I do. I read Speak my freshman year for class and I remember that I enjoyed it, but my tastes were drastically different then; I liked everything. I was less impressed with Twisted, and even more so with Catalyst.

This is due mainly to how Anderson arranges her books: there's a bunch of meaningless ramblings that lead up to one giant, emotional curveball, and the aftermath ends up being more and more nothing. This book's length mirror

Even though I was exhausted, I stayed up until 1:00 AM reading Catalyst. I was all ready to put the book down, then something happened, and there was no way I could stop reading until the end.

Catalyst tells the story of Kate, a senior chemistry geek, who is determined to attend M.I.T. She is so fixated on going to the school of her deceased mother that she applied no where else and did not tell anyone. At the outset of the book, Kate is desperately waiting for a letter from the prestigious Cambr

This is another emotional story written by Laurie Halse Anderson. "Catalyst" is a novel about Kate - high school senior who thinks she has all her life planned out and under control. She is a perfectionist and does everything to make sure her life doesn't steer away from her plan. Some might think that Kate is self-centered and almost obsessive, but in reality she uses this orderliness to shield herself from the deep pain caused by her mother's death. After a series of events, some catastrophic, ...more

After my last read, not to be confused with my last review, I needed something powerful and beautiful and character-driven. Catalyst turned out to be a perfect choice. Until now, my experience with Laurie Halse Anderson consisted solely of Speak. At that time, I didn't really read much realistic fiction, and I mostly steered away from unhappy books. As such, I really was not sure what to make of it, and could not appreciate it as much as I know I could now. Having read and super liked Catalyst, ...more
I’ve reviewed five of Laurie Halse Anderson’s novels so far, and I think I’ve made it clear that she’s one of my all-time favorite YA authors. That said, it’s not difficult to identify a sort of formula. Most of Anderson’s YA novels are problem novels about a particular issue. That’s not necessarily a bad thing - Anderson writes problem novels better than pretty much anyone I can think of. She writes novels that are realistic and relatable, and she never sacrifices character development or an en ...more

Catalyst by Laurie Halse Anderson is an entertaining and adventurous novel for teens and adults. This novel is focused on the life of Kate Malone, a High School Senior who is a straight A student, long distance runner, daughter of the local minister, and new girlfriend to Mitchell “Early Decision Harvard” Pangborn. Everything seemed to be looking up for Kate, she was excelling in school, she had a new boyfriend, there were no major troubles at home, until, one of her neighbor’s houses burned dow ...more

Laurie Halse Anderson has become one of my favorite authors!

Catalyst is about a girl named Kate Malone, the daughter of a preacher, and science whiz is school. Her dreams and aspirations revolve around her acceptance into MIT. The book takes the reader through Kate's trials as she waits for a letter, any letter, from MIT. Just as Kate gets into a groove a tragedy happens. Her neighbors house and barn are on fire!

This book was "okay" in the most okayest way possible. I read it in like 2 days and it was light and easy to read. I did enjoy reading, I guess, but I just didn't really care much about it. There were so many things happening but somehow I couldn't bring myself to care about it. I didn't like how LHA totally shifted halfway through the book. It was like a book about college acceptance and a book about a child's death mashed together with no real correlation. A lot of things happened that made me ...more

Speak was the very first novel I read by this author and though it was a good book, reading the reviews before I actually read it spoiled a lot of things for me, especially the main premise of the story. So, lesson learned, I skipped reading reviews until after I have finished reading the book. This is the reason why I love Catalyst more than Speak.

"Catalyst" is about Kate Malone, the somewhat typical straight-A acheiving cross-country running unsatisfied daughter of a preacher. At the beggining of the book the main conflict comes from the pressure she experiences while she waits to get accepted (or rejected) by MIT. Then, she runs into the ever so unfriendly neighbor girl Teri Litch. That really mixes up the plot, and the story.

While I enjoyed reading this book, it was no where close to as good as Laurie Halse Anderson's "Speak". One of t

I am slowly working my way through all of Laurie Halse Anderson's books and have yet to be disappointed. How she can get inside the minds and think like a teenager AND put it on paper is beyond me! Even having a 16 year old and 12 year old I could never have insight she possesses. Elastic Condition, Scientific Method and Flammability are just a few of the chapter titles which is so intriguing to me. I love the transition between Good Kate and Bad Kate and was totally taken aback and unprepared f ...more

I really enjoyed this book. The narrator was witty but painfully realistic. Everything about this book was real and gritty. Some of the lines were just perfection. I can't think of any more words to describe this book because I loved it so much.

Personal Response:
Honestly, I didn’t feel like this book was outstanding. For me, the book seemed to be all over the place. The book had so many things going on at a time and sometimes it was hard to follow. I was left with many unanswered questions after reading the book. I think the storyline was very interesting and had some great surprises, but it was definitely not my favorite Laurie Halse Anderson book.

Laurie Halse Anderson ci presenta un nuovo romanzo per young adults scritto con il cuore che di certo non potrà lasciarvi indifferenti.

Già colpita da Speak e Wintergirls, non sono rimasta affatto delusa da questo romanzo, e vi posso assicurare che le mie aspettative erano alte.

Le emozioni difettose racconta la storia di una giovane studentessa incredibilmente dotata che ha fatto richiesta di ammissione al MIT: la risposta tarda però ad arrivare e la sua iniziale sicurezza comincia a scemare. Cer
