Books from the Bible that I like:
* Everything written by John
I would say morality is something that is ingrained in every human being. While it's true that some cultures had less of what you might call "modern morality" -- the fundamental things like forgiveness, compassion, empathy, love, etc. and finally the sense of what is right and wrong. These, I believe are ingrained in every human being. While some might choose to be more loving and compassionate, and other might choose not to -- the sense of one being good, and other being bad is crosses cultural and historic boundaries.

Regarding the book: you can use Amazon's "Look Inside" feature to read the first chapter (The Law of Human Nature), which covers the question of right-and-wrong/morality as a universal human thing. Although written from a Christian perspective (I'm a believer), its arguments are valid from a secular viewpoint as well.
I'm a Christian myself and have been one for nearly two two years. I came from a more or less non-religious background growing up and today Christ is of utmost importance in my life displacing everything else.
I look forward to ultimate redemption of mankind - basically a time where every problem in the world will be solved and there will be no suffering. It will be a time when humans and their creator (God) will dwell together and Christ will rule over them with justice and love. I believe there is no human description of this supernatural world, what I assume is that it will be filled with unfathomable joy and splendour.
A few verses from the Bible about it: (http://www.biblegateway.com/passage/?search=Revelation+21...)
(Please bear in mind most of this is symbolic as is the rest of the Book of Revelation)
"Then I saw “a new heaven and a new earth,” for the first heaven and the first earth had passed away ... 3 And I heard a loud voice from the throne saying, “Look! God’s dwelling place is now among the people, and he will dwell with them. They will be his people, and God himself will be with them and be their God. 4 ‘He will wipe every tear from their eyes. There will be no more death’ or mourning or crying or pain, for the old order of things has passed away.” 5 He who was seated on the throne said, “I am making everything new!” Then he said, “Write this down, for these words are trustworthy and true.” 6 He said to me: “It is done. I am the Alpha and the Omega, the Beginning and the End. To the thirsty I will give water without cost from the spring of the water of life." - Revelation 21
Most importantly of all, the price (or ticket) to enter the Kingdom of Heaven has _already_ been paid; by Jesus on the cross.
The core Christian belief is that _all_ humans are sinner (or evil) and that none of us are deserving of anything but death. But God so loved us (his creation), that he decided to save us by taking the penalty of our sin (which is death) upon himself on the cross. (Jesus is an exact representation of God - http://www.biblegateway.com/passage/?search=Hebrews+1%3A3...). He intends to eventually fix everything; this world, and unite us with himself. The good news is that He freely offers us his salvation and all we have to do to receive it is to believe in him.
This oft-quoted Bible verse summarizes it well: "16 For God so loved the world that he gave his one and only Son, that whoever believes in him shall not perish but have eternal life. 17 For God did not send his Son into the world to condemn the world, but to save the world through him."
