Why Trilogies are great!

Not too many, nor too less.

Trilogies are the perfect number of books for a series. Great for plot and character development.

Have a look:

Book One: Intro and Build up; cliffhanger

Book Two: In-a-soup; MASSIVE cliffhanger

Book Three: The final victory/ whatever, conclusion

Easy to buy and maintain, and keeps the reader in the story.

There are exceptions, of course, like the Harry Potter Series and Percy Jackson.

Here are some trilogies you might wanna try out:

Shiver, Linger, Forever, AKA Shiver Trilogy/ Wolves of Mercy Falls

The Shiva Trilogy

The Hunger Games Trilogy

Divergent

Also, you might wanna know that I am working on two fantasy alternate trilogies right now, you guys! *Wink!*
