Have you considered doing events at your local libraries? Libraries are so vital to our literary communities and are a great way to continue your book's momentum. As always, it's a good idea to try and pair an event pitch with something relevant to what the library is already doing or planning on featuring. Do they do local author days, or poetry days? Does your book fit a certain theme or demographic?
Consider trying for a library event a month! Each city's public library system (maybe even branch to branch) has different parameters for proposing events. See what you can find by Googling or event visiting the library and asking directly!
