I have been working with two boys who were abused over a a long period we began at a bout that age the older boy was 11. It is a very difficult process but they are doing so well today. they found a bond with me as a fellow survivor and that has carried some issues of its own. I don't know of any books or materials for that age group but as persons concerned you can remain involved and allow the child to talk about where he is at. the same fears that we as adult survivors face,he will face only in real time. the confusion is pretty much the same and he will probably need to have opportunity to re build trust in most everything. it is always a very individual experience. I wish there were more info for kids, I would be happy to have it too, but I would be happy to share what I can from experience just pm me.
Towards thee I roll, thou all-destroying but unconquering whale; to the last I grapple with thee; from hell's heart I stab at thee; for hate's sake I spit my last breath at thee. let me then tow to pieces, while still chasing thee, thou damned whale! Thus, I give up the spear!"
