In the four volumes of The Power of the Holy Spirit, Don DeWelt takes an in-depth look into every reference to the Holy Spirit in the Bible. If you are looking for an educated, in-depth, completely Biblical study on the Holy Spirit, or if you are looking for some theological reading for your high schoolers, this is the best resource on the Holy Spirit, apart from the Bible itself, that I have found.
Now, College Press is offering ALL FOUR COMPLETE VOLUMES as PDF downloads, along with four volumes of Personal Worship by Don DeWelt and two books by Herbert Casteel. All 10 titles as completely free downloads.

Happy Reading! :-)
