Is Huckleberry Finn banned in California?

I'm curious, is it true that the classic novel "Huckleberry Finn" by Mark Twain is banned in the state of California? I've heard conflicting reports and would love to get a clear answer. Are there any official regulations or laws in place that restrict access to this literary work in the Golden State? And if so, what are the reasons behind such a ban? I'm genuinely interested in understanding the situation and would appreciate any insights you might have.
