I was the worst kind of hypocrite, acting like I had all this moral authority. Meanwhile, I was a lying liar of lies, sitting on a throne of lies, eating lie soup and liar cake.






MOTION, the latest release by Penny Reid is filled with her signature humor and oddball quirky characters. There are plenty of laugh out loud moments throughout the story and while the steam level is lukewarm, the story is what will hold readers’ interest.

I love Penny Reid’s humor. I love her odd, brilliant heroines. I love the men who dig their quirkiness. I. Loved. This. Book. What a great start to this series! I knew virtually nothing about Motion going in, and I highly recommend that approach.

Mona is a delight. An introverted and socially awkward genius with a strong moral compass, she uses hilarious techniques for coping with uncomfortable situations. I love how her mind works. Mona is book smart, but people confuse her; therefore, her deci

Title: Motion
Series: Laws of Physics #1
Author: Penny Reid
Release date: February 11, 2019
Cliffhanger: YES
Genre: Contemporary romance



This is the first in the Laws of Physics trilogy, and as you would expect in a three book story arc, you're going to be left hanging in suspense a couple of times. I'm not gonna lie, Penny had me more than a little concerned about this cliffy she was warning us all about on social media. It got to the point where I was dreading the end of the book.

A Penny Reid book is like a bar of my favorite chocolate – certain to never disappoint! I sat down last night to read my arc of Motion, all giddy because I finally had time to curl up with it and a cup of tea. I was expecting to love it but I wasn’t expecting to be so completely addicted to Mona’s narration and the hot, smart, yumminess of Abram, that I ended up devouring the book in one sitting. Mona is one of Penny’s smartest characters yet and she had me laughing out loud at her physics jokes ...more

The build up in this story is just... perfect. I’m SO not a fan of cliffhangers but it makes me sad to think that if I would’ve let that stand in my way, I would’ve missed out on Abram and Mona’s story. The story is told in that distinct Penny Reid voice: intellectual, witty, deep, analytical, and at times even vulnerable.

There are so many facets to the characters and we get to explore them in a way that really enhances the tale. Abram’s got this openness that sucked me right in. He’s not a pus

Favorite Quotes:

Talking to her was like arguing with a flat-earther. Ignorance plus arrogance is why we can’t have nice things!

Gabby was a nebulous assemblage of unscrupulousness and exasperating nonsense, and we’d likely never be friends again, but she was undoubtedly charming when she wanted to be.

My Review:

I am awed, enamored with, and flummoxed by Penny Reid. She is the only wordsmith I know who could simultaneously create tension and levity with prunes, Moby Dick, and whale poop. She has st

Part One of Three.

This was an enjoyable installment in the same world as Katlyn Parker and Martin Sandeke’s romance from the “Chemistry” series. Mona is a twin, the nerdy half of the duo, and the daughter of famous singers. When her twin, Lisa, is arrested, she asks Mona to pretend to be her for a week so her parents don’t find out she’s in jail. But during that week, Mona falls for Abram, the best friend of their older brother, who their parents have hired to watch out for “Lisa.” This was cute

The road to hell is paved with good intentions. Okay, so Mona is super focused. She's obsessed with all things physics and relativity and scientificky gobbledygook. Most of it is way over my head, but that's not the point. The point is that this girl is a genius and never really had the chance to be 'normal'. When her twin sister, Lisa, calls her because she got herself in a bit of a pickle, she's a bit resistant. Pretend to be her? They haven't done that since they were kids. Shoot, they barely ...more

Why did I do this to myself? That ending has me all kinds of crazy and I need more of this story ASAP! Mona and Abram had me on the edge of my seat this entire book and I was just waiting for their tension to finally explode into heated passion. I so need them to get an HEA and finally learn all of the secrets that were floating around this story. I have to say, this may only be the first book in their trilogy but I already know they're going to

Maybe it was because we were warned extensively that this cliffhanger was going to be bad but.. it wasn't that bad? I mean, it was !!! but I think I was also expecting something very different.

That said. I didn't love this. I don't read blurbs (or if I do it's ages before I actually read the book so the details are hazy but in this case I legit had no clue, only that it tied into previous series) so I was unprepared for the direction the plot went.. and while I don't mind the trope, in theory,

Laws of Physics was a book that I’d been waiting YEARS for. I wanted Abram’s book so bad back when Elements of Chemistry came out and I waited year after year, watched it get pushed back again and again and I just kept holding on, hoping that the wait would be worth it and that it would be everything that I dreamed.

Unfortunately, this first novella was nothing short of a nightmare for me.

I wanted to love it soo bad. You don’t understand how badly I wanted to love this book. But while I did lik

Penny Reid never fails to deliver a charming and fun romantic page-turner for smarties.

Despite being identical Twins, Mona and Lisa DaVinci are nothing alike. Mona is a physics genius who is starting her PhD at the tender age of 19, while Lisa dropped out of high school and is in desperate need of assistance. She convinces Mona to impersonate her for a week while being babysat by her older brother’s best friend, Abram.

There’s only one problem, besides being a talented musician, Abram is annoyi

I'm so ready for the next part now.

Omfg that ending though!!! I have no excuse, I was warned but I couldn't do the sensible thing of delayed gratification, waiting until all three parts are available because my greedy little eyes needed to read the newest Penny Reid the very moment it arrived. So I did. And now I wait. Impatiently. Gah.

Damn this was compelling, I was completely obsessed with it, couldn't leave it alone.

I have no words. I'm actually speechless, but guess what? I learned some new ones while reading this. Who knew physics could be so damn HOT!

Also donuts. Like, COME ON! That scene had me screaming at 3am.

This book was an incredibly written tale of a chemistry so strong that no amount of scientific literacy could snap it.

I’ll be honest…I was scared to read this book. Scared mixed with a lot of excitement – scarecited? Sure…we’ll call that a new Penny Reid induced emotion. I knew after the Elements of Chemistry Series almost destroyed me that the Laws of Physics Series was probably going to have the same effect. I can officially state this is 10000000% accurate and I’m epically and totally screwed (in the best w

"So . . . it has come to this.”

Why, why, why did I start this book now? I knew I should have waited for the others to be released, but nooooo, I had to read it NOW. And again, PR never fails to draw me in and delight me with her writing. Only now I will remain unfulfilled for weeks until the next one is released. And reading the little blurb about what's to come only has me more anxious. GAH!!! How about a ARC??!!! Have mercy on me. ;)

You're definitely going to want to read this...

You'll probably yell something unprintable when you get to the end, and maybe throw a thing (not your kindle please, or anything sharp) - but because you will have laughed out loud, and your heart will have pounded a little or maybe a lot while you read this wonderful Penny Reid book, you'll forgive her for a brutal cliffhanger and be very glad you got to hang out for a while with the wonderful characters she creates.
Bookphenomena (Micky)
So there’s Mona and then there’s Lisa and in this book you get a slice of both of them. MOTION quickly launches you into the quirky, intelligent world of Mona. She feels initially one-dimensional and she is definitely somewhat emotional stunted but there’s lots to unwrap with Mona, her quirks, her quips and her insecurities. I like Mona, a lot and I feel like I’ve only just scratched the surface.

Abram is the house-sitter but really the minder and chaperone employed to keep ‘Lisa’ in line. He’s n

Every time I pick up a Penny Reid book, I know I'm in for a unique story with interesting characters and great banter. This book was everything I expected and more. The banter, the slow-burn romance, the twin swap, the cliffhanger.... Every bit of this book was fantastic! What a great start to this series and I can't wait to see where this story goes!

OMG. Loved this one! It ends on a cliffhanger and I am dying for the next book. Mona’s inner thoughts are absolutely hilarious and punny, making her a great romance narrator. And Abram? I’m dying to learn more about him, as well as the side characters

This is a steamy, cute read with LOADS of unresolved sexual tension (my favorite romance trope). While the plot is fun, nothing really gets resolved in this book, but the summary itself explains that its part of a series, so no disappointment there

So . . . it has come to this. I already knew I had a Penny addiction before starting Motion, but not all addictions are bad... right?

I usually devour Penny’s books as soon as they’re released but I can’t deal with cliffhangers, so it’s been torture having to wait for all three instalments of Laws of Physics to release before I could dive in. Then again, Motion was absolutely worth the wait!

Motion is the first book in the Laws of Physics series. If you're reading this review, let me warn you that this book ends up in a cliffhanger. I was warned beforehand and, I understand it had to be done at that precise moment, but I still need the second book in the series like air. So, if you don't like cliffhangers, maybe you should wait until the three books are released.

The day that Mona received a phone call from her twin sister, she knew she couldn't deny her anything. What she didn't kno
