There must be an extraordinary number of house plant books, and while many of those are well worth the time, some are required in your library. It's nonsense to dismiss any such resource-guide as worthless if it does not excel in this or that: it's often wise to relay on a variety of such books so that you can compare information.
That all said, this is sure to be a staple in many bookcases, because it offers comprehensive and concise information regarding plant identification, basic growth necessities per plant (lighting, water, humidity, soil) or even plant groups (such as Succulents or Philodendrons, one of my favorites). The range of material is varied and includes all well-known and lesser-known plants that'll do well in your house or greenhouse (or even terrarium, which I do recommend, by the way).
Furthermore, there are additional chapters on for example diseases and what to do about them, displaying indoor plants, etc.. Inside these chapters can be found a wealth of information for beginners and experts alike. But what defines beginner or expert I'll leave to others.
The House Plant Expert even offers golden rules ... each his/her own rules, but you won't hear me arguing with these.
Anyway, for people growing tropical plants, I found out that they adore frequent misting, diffused sunlight, high humidity, company of each other, and room to grow (watch out for Monstera Deliciosa, that one goes fast and all over the place). And do invest in the right soil types; that makes a difference.
