On the tip of my… brain

You know when you have a memory of something, but it's so fleeting that you can't seem to grab it? Like when a word's on the tip of your tongue, but, you know, not a word… and not your tongue…? No? Oh.

Well a novel popped into my head earlier and now it's driving me mad. It's a teen novel from the 80s (I assume) and I think (though I'm not certain) it was called Apple of My Eye*. I have a vague sense that it may have been free with a magazine (although I'm not even sure they did that back then) and the cover I'm picturing was lilac (maybe) with (perhaps) a pencil drawing of a teenage girl (or, you know, something else…).

Anyone? Bueller? Or – more likely – Luisa?

* It's not the Apple of My Eye by Helene Hanff or Carla Neggers.
