Query: Let's All Not Bother

A self-indulgent conceit from a highly successful and respected author who knows he does not have to try very hard any more. All the characters speak with the same voice. The story leads nowhere and says nothing. The many fantasy elements are used not to illuminate truths, which good fantasy can do, but as an excuse for implausibility and incoherence. The one saving grace of the novel is the affectionate description of some aspects of Los Angeles history and geography. The passages about Mount Lowe are fascinating to anyone who lives here. But if I want to learn more about my adopted city I'll look to a guidebook rather than a third-rate fantasy thriller. There is no doubting Bradbury's greatness. How sad that he now feels able to reel off routine dross like this.
