For a 7th grade (that should be when you were 13 i suppose? correct if i'm wrong.), it's a very well-written piece.
The first stanza was very nicely rhymed, and a nicely tuned sonnet. (:
It strayed a little in the second stanza due to a lack of rhyme.
And the last... i think it's too short.
Okay, ignore me >< I don't really know how sonnets work, but seen them online. tend to be a little long.
But I think your sonnet is sweet.
Keep writing alright? write for yourself, not for others.
Don't stop because there aren't readers, or rather, there aren't reviews. You're the most authentic reader of your writes.
I don't know who olivia benson is, but from the way she is described, i think she's some sort of investigator or PI in a police force. Those who go round investigating murders and searching crime scenes. Which sort of reminds me of deka wanko (japanese drama).
