Whether you’re looking for a gal pal who knows her gossip or an assertive female figure to look out for you during the next few months, TheWB.com’s bringing you two enchanting girls named Summer who are just as refreshing as the season after which they’re dubbed.

Summer Glau
Why she’s a catch: On Terminator: The Sarah Connor Chronicles, Summer Glau plays Cameron – a Terminator assigned to protect the future leader of the human resistance. She’s a robot, but her human-mimicking capabilities make her appear warmer than many a homo sapien! Oh yeah, and to further amp up her cool factor, Summer’s Firefly character River Tam knows how to make her way around a spaceship.

Moment in the sun: In TSCC‘s “Gnothi Seauton”, she exhibits a striking combination of fortitude and compassion by admonishing a family of humans to “Remain calm”…before removing her face from the windshield of their car.

Summer Roberts
Why she’s a catch: The O.C.’s Summer Roberts is played by the ever-alluring Rachel Bilson. Even though Summer’s quip-filled relationship with Seth Cohen plays more like a handy tennis match than a fairy tale romance, she expects to be treated as a princess. High maintenance? Sure. Worth the drama? Well, Seth did name his boat – the Summer Breeze – after her!

Moment in the sun: In The O.C.’s “The Rainy Day Women”, she manages to make a lemon meringue bride’s maid dress look kinda chic. And that takes a whole lotta charisma!
