Parker makes a decent small bow but my pic would be a Rintec by hoyt. Also the browning and Alpine youth bows are nice. My girlfriend started with a Alpine Micro and moved to a Rintec. Both decent bows but the Rintec is much nicer. Of course it cost almost twice as much though.

Don't get a walmart bow, if she is serious about go to a pro shop and have it set up for her, but get one that can grow with her. All of the ones I mentioned should work fine.
