The 55MB demo of Bookworm Adventures 2 provides 60 minutes of the word-building puzzler before demanding that you pony up $19.95 for the whole shebang. If that seems a little steep, just wait--PopCap will be releasing each of the game's three chapters as individual episodes come August 19, though pricing is not yet confirmed.

Meanwhile, the sale on Bookworm iPhone (normally $4.99) will run until August 5.
