If you want TimKon, check out the original Young Justice comics(not the show, the show is completely different), or the incarnation of Teen Titans that follows directly after Young Justice. Red Robin has a little bit of TimKon in one or two issues, but it's mostly just Tim. This person on tumblr has download links for all of Young Justice and Red Robin (click on the title of the series you want on the side): [link] Teen Titans can be downloaded here if you have can download torrents: [link]
There's no place (that I know of) where you can actually read these online, so sorry if that's what you're looking for.
Sorry, I don't know anywhere online to read it. Unless you want to buy it from DC's digital comics store, but 55 issues at $2 each gets kinda expensive. The first issue is free though, if you want to just get a feel for it.
