Do you recall ever starting reading a book and getting very excited about it? It was all you ever wanted. It had a great original plot that had always surprised you; it had accurate and suggestive descriptions of sceneries and events making you feel as you were there; it had amazingly built characters with deep personalities and a past you could relate to.

Though, it was quite confusing because there were certain references you could not understand and some characters kept appearing without any details about who they were and the narrator acted as if you were supposed to already know them. Well… that is because you really were supposed to.

Book hunting

Because after you finished the book and looked it up online or discussed it with someone who also had read it, you found out that it was the second volume of a series – in the best case – or the 15th volume – in the worst case. And suddenly you had to hunt for all the other books. Sometimes the early ones were not even translated in your language or they were just not that popular and they were pulled off the shelves or they were too popular and people devoured them.

Indubitably, you were not that eager to wait days, if not weeks or months, to get the first volumes. Sometimes you actually had to jump from the 15th volume to the 7th, then the 16th, the 3rd, the 9th and so on until you got your hands on the first issue. When there is no connection between the books or when there is a slight tie between them and there is only a shift of the main characters, it is ok.

You either needn’t read them in a specific order in the first place or you might need to constantly carry a piece of paper and a pencil on you to remember where you have heard of that character before. But when the action focuses on one single character and his evolution… well… you are doomed. Doomed to find them all, catch them like Pokemons and perhaps reread some of them. But this is only in the case you do not mind the confusion and you are just happy to discover the adventures you missed.

A Time for Everything

book readingA quote from the book which has sold over 5 billion copies, the Bible, says that “There is a time for everything, and a season for every activity under the heavens”. And this is what is amazing about book series. One book usually points out an important event from the main character’s life.

Now depending on the length, it might illustrate his entire life and reveal more interesting aspects about him and the secondary characters. But when it comes to book series, they take their time. They start with birth, first word, first step, childhood, teen years, first kiss, first huge failure, entering adulthood, real life problems and so on. And even when there are over 100 volumes, there are still so many things to say and discover, because this is how life is and fiction just makes it better.

If only we lived enough to be able to read all of the series we want… But if you are currently torn between which book series you might want to start reading, we are here to suggest you 10 of those successful series sold in more than 100 million copies.
