ok, first, i am assuming you have read the book. If i were you i would write it in third person view, (he, she, it, ie. susan, peter. or did you
mean like from the point of peter, reepicheep(is he in that book?)lucy, etc. also, i would mention the concept/argument of the Narnia allegory WITHOUT giving opinions.
hope this helps, if it doesnt, tell me
p.s.- narnia allegory- whether c.s. lewis meant them to be like the accusation, conviction, and ressurection of christ. there is lots about this online. go to google, type in About(the website i found info abuot it)-Athiesm/ c.s. lewis, or something like that!!
hope your paper goes well
