I think I'm Science Fiction/Fantasy starved.  Can anyone please suggest some good books.  I don't like stuff that's depressing (Ray Bradbury - sorry), strongly supernatural, or that contains much (or any) sexuality.  Thank you for the help!

I'll give you some light reads that are my favorites (I put PBS links to the books), I wouldn't say any of them are too depressing:

The Accidental Time Machine by Joe Haldeman - Easy reading, not depressing.

Dean Koontz's new Frankenstein Series is wonderful.

The Maxiumum Ride (young-adult) series by James Patterson

The Neverending Story by Michael Ende

Thank you for the suggestions, I'll have to check these out!  I've read some of the Maximum Ride books and I really enjoyed them.

Hm.  While The Accidental Time Machine doesn't hold a candle to some of Haldeman's other novels, be warned it does have some explicit sexual content.  

Have you read any of the classic Science Fiction works by H. G. Wells?  Titles include the Time Machine and the War of the Worlds.  He published others, but those are probably the best known.

Hmm...... I don't recall the sexual stuff in The Accidental Time Machine, but then again sexual stuff rarely bothers me, so I may not recall that.

If you liked the Maximum Ride, you might like the Ranger's Apprentice series by John Flanagan. Both are ya, but RA is more a fantasy, but with very little to no magic. An alternate Britian. I really enjoyed it and it seems to fit the criteria you listed...

Thank you for the additional suggestions and the warning on The Accidental Time Machine.  I have read The Time Machine but not War of the Worlds.  I think I need to try some Asimov too.  I loved I, Robot but didn't like Nightfall at all.  Ranger's Apprentice looks good too.  I love fantasy!

Coming in a bit late, but you may want to check out a relatively new author named Kevin Rau. He's starting a series; the first book is HERO's Metamorphosis. Read it a couple weeks ago and it was an easy read, light hearted overall though with good action and had fairly mild sexual content (kissing, a character thinking they'd like to spend the night with someone, flirting - but nothing beyond that).

Don't laugh at this suggestion, try William Shatner's Quest for Tomorrow series.  If you want science fiction that will make you laugh like the 5 books in the Douglas Adams' trilogy  try reading Red Dwarf and Better Than Life by Grant Naylor. 

Check out the novels of Stephen Baxter or Gregory Benford. My favorite SF authors are Fred Pohl, Isaac Asimov,Arthur C. Clarke, Poul Anderson, Jerry Pournelle, Michael McCollum. Be sure to friend me and check out my posted books.

Happy Reading!

James White the sector general series.  No sex other than noticing that one of the characters has a pleasing shape.  Engrossing books about life in a multispecies hospital.

Try anything by Andre Norton. Well written and always entertaining.  

BEST SERIES I THINK ARE BY TERRY BROOKS AND DAVID BREWER OR JOHN RINGO

Try "Old Man's War" or "The Android's Dream" by Scalzi (maybe slightly off on the spelling)
