Attraction

2015

This is a previously\-published edition \- ASIN: B00UPU50EQ He is everything she doesn’t want, so why does she want him so badly? From the New York Times Bestselling Author Penny Reid One week. Private beach. Invisible girl. Jerk\-faced bully. What’s the worst that could happen? Kaitlyn Parker has no problem being the invisible girl, which is why she finds herself hiding in various cabinets and closets all over her college campus. Despite her best efforts, she can’t escape the notice of Martin Sandeke—bad boy, jerkface bully, and the universe’s hottest, wealthiest, and most unobtainable bachelor—who also happens to be Kaitlyn’s chemistry lab partner. Kaitlyn might be the only girl who isn’t interested in exploiting his stunning rower’s build, chiseled features, and family's billionaire fortune. Kaitlyn wants Martin for his brain, specifically to tabulate findings of trace elements in surface water. When Kaitlyn saves Martin from a nefarious plot, Martin uses the opportunity to push Kaitlyn out of her comfort zone: spring break, one week, house parties, bathing suits, and suntan lotion. Can she overcome her aversion to being noticed? Will he be able grow beyond his self\-centered nature? Or, despite their obvious chemistry, will Martin be the one to drive Kaitlyn into the science cabinet of obscurity for good?

Elements of Chemistry

Heat

2015

It’s too late to turn back now . . . From the New York Times Bestselling Author Penny Reid Four days left. Private beach (…and boat). Not so invisible girl. And maybe less of a jerk-faced bully than originally thought. What’s the worst (or the best) that could happen? Kaitlyn is finding life outside of the science cabinet of obscurity to be quite illuminating …and so are her pants. When things heat up between Kaitlyn Parker and Martin—previously known as the jerk-faced bully—Sandeke, she places her trust in the one person she never thought capable of earning it, let alone keeping it safe. Fortunately or unfortunately for Kaitlyn, where she gives her trust she can’t help but also give her heart. But how will the world beyond the sanctuary of their newfound connection react to their relationship? Soon senators, chinless billionaires, and elements beyond Martin and Kaitlyn’s control want to weigh in on the young couple’s future. Navigating the chaotic inferno of new love might be more than Kaitlyn bargained for, and much, much more than her trust—or her heart—can handle.

Elements of Chemistry

2015

He broke her heart, and now he’s back . . . From the New York Times Bestselling Author Penny Reid One week. Manhattan apartment. Super-hot ex-boyfriend. …What’s the worst that could happen? It’s been nine months since Kaitlyn Parker has seen or heard from Martin Sandeke—nine months and five stages of matter. She’s lived through the worst of first-love heartbreak, and is most certainly stronger (and less likely to hide in science cabinets) than ever before. But now Martin is back. And he wants to be friends. But he’s sending mixed signals to the Bunsen burner in Kaitlyn’s pants. Will Martin re-capture Kaitlyn’s heart? Can Kaitlyn and Martin ever be just friends? Or, despite an abundance of chemistry, are some bonds just too unstable to endure? Elements of Chemistry: CAPTURE is the final part in a three part series; it is 65k words. Part 1 (ATTRACTION) Available Now! (ends on a cliffhanger) Part 2 (HEAT) Available Now! (ends on a cliffhanger) Part 3 (CAPTURE) Available Now!

_Forced to lie to protect her sister . . . From the New York Times Bestselling Author Penny Reid_ One week. Home alone. Girl genius. Unrepentant slacker. Big lie. What's the worst that could happen? Mona is a smart girl and figured everything out a long time ago. She had to. She didn't have a choice. When your parents are uber-celebrities and you graduate from high school at fifteen, finish college at eighteen, and start your PhD program at nineteen, you don't have time for distractions outside of your foci. Even fun is scheduled. Which is why Abram, her brother's best friend, is such an irritant. Abram is a talented guy, a supremely gifted musician, and has absolutely nothing figured out, nor does he seem to care. He does what he feels, when he feels, and—in Mona's opinion—he makes her feel entirely too much. Laws of Physics parts 1 (MOTION) & 2 (SPACE) end with a cliffhanger. Part 1 (MOTION) will be released February 11, 2019 (ends on a cliffhanger) Part 2 (SPACE) will be released March 11, 2019 (ends on a cliffhanger) Part 3 (TIME) will be released April 15, 2019
