Initially this book was interesting but later it became too boring. It is too long in my view.
I also think that the novel is unequally developed when it comes to advances in interstellar travel and biology. For example, when ship finds aliens and take their samples, they need to send it back to their planet to do a genetic analysis. It is highly unlikely that humanity could achieve an interstellar travel capacity and at the same time could not develop technology that could sequence alien biological forms on board of their ships.
