Lissa can?t see hers, but with a touch, she can see your true love. After a lifetime of heartbreak, will she let herself love again?

This is more of a tagline than anything since key elements of a logline are missing.

I wouldn't end a logline with a yes or no question, especially if it is rhetorical.

Try saying it a different way, fore instance instead of, "Will she let herself love again" you could say, "She must overcome her fear of a broken heart." Then add the other elements around it.

"After meeting a handsome reporter, a lonely psychic who can only see the destiny of others must overcome a broken heart if she's to find true love." (That's still clunky but I hope you see where I'm going)

But when you end the logline in a question it sounds like a line from the old Batman TV show: "Will Batman escape? Will Gotham be saved? Or will this be the end for our Caped crusader? tune in next week and find out!

(I've done the same thing)
