One year after Melville struck gold with Typee, his first novel and a colorful account of life in the Polynesian islands, he published Omoo. Melville's success with Typee, while not stratospheric, was significant enough for his publisher to print Omoo sight unseen. Unfortunately, Omoo is a prime example of the dreaded sophmore slump so feared by artists. Omoo is more of the same subject matter found in Typee, but as we all know lightning rarely strikes twice in the same place. Omoo is a pale imitation of Typee.
The main issue is Omoo lacks a unifying theme, such as Melville's captivity on a tropical island which gave Typee a core. On top of that, Melville tales (or yarns, depending on how much truth you believe are in these pseudo-autobiographical novels) this time out are not nearly as interesting as those found in Typee. I was pretty bored with Omoo for many of its pages.
Melville's writing is just as crisp and immediate as it was in Typee, but this book centers more around Melville's wanderings in Tahiti than it does on Polynesian life. Other sailors and the colonial towns are really at the forefront of this book. There's more commentary on the missionary movement which may be interesting from a cultural standpoint but it just doesn't come alive.
I found some of the items Melville touches on interesting from time to time, but the overall travelogue feel of this book - which Typee largely managed to avoid - means Melville can't develop any of them. For example, a Polynesian joins Melville on a ship as they leave the Marquesas, and this man's homesickness is touching. However, the character just vanishes at some point, and I don't even remember where or why. Another example is the author's meeting with Pomaree, the Queen of Tahiti. There's a big build up to this meeting, but the pay-off is a drab let-down.
Omoo was a modest success for Melville due to it being enough like his first book to lure readers back for a retread. Most modern readers should probably read Typee and skip Omoo.
