As Sacramento continues to grow, there's a lot of talk about gentrification and whether it's good or bad. Change of any kind, of course, can be good, but certain kind of changes are devastating communities across this country. A professor at American River College takes on the topic of gentrification and how it affects communities in her new collection of poetry, "Salvation on Mission Street."

The book, a first for Cathy Arellano, will be released this weekend at the SummerWords Writing Festival. Arellano, who will read from the new book at SummerWords, grew up a Mexican lesbian writer in San Francisco's Mission District and has first-hand experience with gentrification. Her mother was evicted from the flat they rented in 1983 by new owners and died less than a year later. Arellano returned to San Francisco as an adult and the book's poems and stories reflect the love she feels for the people and places of Mission Street. On Insight, Cathy Arellano talks about her work.
