You can keep the book if you are a caster in order to practice your research skill
Give one to her to get some exp and the Concordance of Research. You can then sell the book back to her for about 8pp or so (you can keep RuneScape Gold if you are a caster in order to practice your research skill).
Another good area around level eight is the fields near the Minotaur Caves in Steam font. In this area are Earth Elementals, Harpies, Skeletons, as well as some Minotaur’s.
You can hunt here solo, but a group is safer as there are usually never guards in this zone (they are all dead by the hands of high level power gamers).
Faydwer - There are a couple good areas for this level range on Faydwer. Firstly, you have Crush bone. At level 10 you will want to fight higher level Centurions near the castle.
At eleven and up you should group and either fight Legionnaires outside the castle, or try to take the Throne Room inside. This area will level you up to fifteen easily.
Next up, the Chess Board in Butcher block is very good from thirteen up. You will want to only fight Undead Pawns, or get a group to try out different spawns.
When you get closer to fifteen, you can try the Lard Trash in Unrest. Just be very careful since there are many deadly trains here, and the beetles will gang up on you for attacking Undead.
