The books are full of every type of person one might imagine. There are the protagonists, who have a tendency towards hubris and recklessness, but are genuinely good at heart and would gladly assist her (though there'd be a slight risk of them taking over). There are the smaller characters, but those are sometimes hard to get an accurate read on. But, after a few hours, she'll have a few promising options.
There's the minor god from the first pile of books she's found. He seems kind, though it's not always obvious, and has a fondness for children. He's also powerful enough to protect them if any threats exist here, though his magic isn't good for much else.
There's a fairy around Rabka's age. She has a four year old son and is notable for her utterly unbreakable determination and general optimism.
There's the matriarch of a clan of wyverns. She's gentle and wise and was willing to take in a lost fairy child when no one else would.
There's a friendly, inquisitive scientist from fairyland's companion world, Earth, which occasionally sends in visitors. She'd be delighted by the magic here and is responsible enough to look after a child.
There's a singer from a world where everything is, at it's core, made of music. He can convince the world to conform to his whims with a beautiful enough song and delights in this ability. He's good natured, though a bit distractible.
