Giorgina gaat met haar ouders, broers en zusjes naar Bloemendaal verhuizen. Met pijn in haar hart moet ze hun oude, vertrouwde omgeving in Enschede achterlaten. Giorgina vindt het maar niets in Bloemendaal, tot dat ze Samuel ontmoet en haar leven een heel andere wending krijgt.

"I don't think we've met," He holds a hand out, "I'm Chase Matthews, the 3rd" He announces grandly. "And I care... Why, exactly?" I say, looking down at his hand and not shaking it. "Uhhh... Chase Matthews? The 2nd richest billionaire in the world?" He asks me as if I'm automatically supposed to know, "Yeah, that's my dad. I'm basically a celebrity." He says smugly and arrogantly. "Pardon me, but you've obviously mistaken me for someone who gave a damn." Meet Kat; feisty, sarcastic, and couldn't give a damn. Meet Chase; spoiled, rich, and the world's most lovable player. Chase wants Kat. Kat wants nothing to do with Chase. How will Kat react when she finds out that she has to spend a whole summer with the bane of her existence and live in the same beach house as him? That is one of many crazy things that happen That One Summer.
